COMPANY PROFILE / OPTICAL COMMUNICATIONS & PHOTONICS

Lumentum
Using its volume in laser chips to claim the "optical heart" of the AI data centre

Lumentum is an optical components maker that builds, in house, everything from the semiconductor laser chips that generate light inside an optical transceiver, through the transceivers themselves, to optical circuit switches (OCS) for data centres. Revenue for its fiscal year to June 2026 was US$3,014 million, up 83.2% on the year before, and in March 2026 it received a US$2 billion investment from NVIDIA together with a multi-year purchase agreement. This profile sets out what the company is putting into optical communications and photonics, who it works with and where it is heading, using only its statutory filings with the U.S. SEC and its official releases.

Sources: Form 10-K for the fiscal year ended June 2026 (filed 17 August 2026), Form 8-K (filed 2 March 2026, including the joint release with NVIDIA), the full-year results release for the year to June 2026 (11 August 2026) and two official releases about ECOC 2026 (21 September 2026), used as primary material.

The one thing to grasp first

Companies in optical communications and photonics fall into three broad groups: optical components & modules, chips & foundries, and network systems & carriers. Lumentum belongs to the first, optical components & modules Sourced. What sets it apart within that group is that it makes the laser chips at the heart of an optical transceiver in its own wafer fabs. The 10-K splits revenue into "Components" and "Systems", and in the year to June 2026 Components accounted for 66.5%. The company says that 78% of the growth in Components came from higher shipments of laser chips and laser assemblies, and that the shift to 200G lane speeds for AI data centres also lifted average selling prices slightly. In other words, Lumentum is easier to understand as a company that supplies lasers to optical module makers than as a company that simply assembles and sells optical modules.

2. The logo and how the name is written

The Lumentum logo is a trademark of the company. We have not recreated it with generated imagery; the image was taken from the official website and is placed here as img/lumentum_logo.svg.

A note on names: the name in the statutory filings is Lumentum Holdings Inc. The company was created in 2015 when the optical components and laser businesses of JDS Uniphase (JDSU) were separated; what remained of JDSU was renamed Viavi Solutions. Japanese-language coverage writes the name phonetically in katakana; this series uses the Latin-alphabet name throughout. In Japan the company has a wafer fabrication facility in Sagamihara, Kanagawa Prefecture, and the 10-K lists Japan among its main manufacturing locations.

3. Where the company sits in optical communications and photonics

Three types of company in optical communications and photonics All are "optical communications companies", yet where they handle light differs completely Optical components & modules Chips & foundries Network systems & carriers Parts that send and receive light Chips linking electronics to light Build and run networks with light Lumentum / Coherent InnoLight / Ayar Labs, others NVIDIA / Broadcom TSMC / Intel, others NTT / Ciena Nokia / Cisco, others Volume lasers, optical packaging Own the switch and GPU platforms Long-haul and network know-how Heavy reliance on big customers Often rely on outside optics Fast change inside data centres Lumentum sits on the left: it makes laser chips, transceivers and optical switches in house Of US$3.01bn revenue (year to June 2026), about 2/3 was components such as laser chips, 1/3 modules
Fig. 1 The three types of company in optical communications and photonics, and where Lumentum sits. The classification is our own, and the example companies are drawn from those covered in this series Our calculation. That Lumentum's core business is optical components and modules, and that it sells into three areas (inside the data centre, between data centres and long-haul networks), is based on its Form 10-K for the year to June 2026.

Looked at by where in the optical landscape it operates, Lumentum spans four areas Sourced.

AreaMain products (as described in the 10-K)Position
Optical interconnect inside the data centreHigh-speed laser chips, optical transceivers, optical circuit switches (OCS), high-power lasers for CPOThe fastest-growing area today
Data centre interconnect (DCI)Coherent pluggable transceivers, and the narrow-linewidth lasers and coherent components that go inside themBoth its own products and component supply
Long-haul and telecom networksROADMs, optical amplifiers, tunable transceivers, pump lasers and products for undersea cablesThe traditional business, selling to network equipment makers
Beyond optical communicationsIndustrial fibre lasers and ultrafast lasers, and VCSELs for 3D sensing in smartphones and other devicesCovered only briefly here

4. Scale

Almost all of Lumentum's revenue comes from optical and photonic products, so the company-wide figures are effectively the size of its business in this field. They do include industrial lasers and 3D sensing, however, and the 10-K does not break those out separately from optical communications Sourced.

Capital expenditure (purchases of property, plant and equipment)133.0231.0451.3
A warning: the huge loss in the year to June 2026 is not an operating loss

The net loss of US$6,935.1 million for the year to June 2026 was not caused by weakness in the underlying business Sourced. Operating income for the same year was a profit of US$524.8 million. The loss comes from a US$7,756.6 million loss on debt extinguishment, booked in the fourth quarter when the company negotiated privately with some holders of its convertible notes and exchanged the notes for about 10.6 million shares of common stock. The company explains that this was a one-off, non-cash loss arising because the rise in its share price had pushed the conversion value of the notes far above their principal. When reading the revenue and profit trend, this one line needs to be set aside.

Employees (27 June 2026)HeadcountRevenue by region (year to June 2026, by ship-to location)Share
ManufacturingAbout 11,916United States20.8%
Research and developmentAbout 1,085Thailand20.8%
Sales, general and administrativeAbout 756Hong Kong17.2%
Total (full-time)About 13,757Mexico / China / Japan14.7% / 9.4% / 3.5%

Regional revenue is assigned to the country where the product is initially shipped, not to where the customer is headquartered. The 10-K notes that the high shares for Thailand and Mexico reflect direct shipments to customers' contract manufacturers Sourced. Cash, cash equivalents and short-term investments at the end of June 2026 were about US$2.7 billion, up about US$1.9 billion in a year (results release).

5. Resources committed to optical communications and photonics

For the four angles this series uses (people; money; outside investments, acquisitions and joint ventures; universities, research institutes and public funding), we separate what could be confirmed from what could not.

AngleDetailsCategory
PeopleAbout 1,085 in research and development and about 11,916 in manufacturing (27 June 2026). No figure is disclosed for staff dedicated to optical communications aloneSourced
Money (R&D)R&D expense of US$356.5 million (year to June 2026, up 17.3%). The company attributes US$19.9 million of the increase to new R&D programmes. Priorities are high-speed and high-power laser chips for AI, high-speed optical transceivers, optical circuit switches, and high-capacity ROADMs and tunable lasersSourced
Money (capital expenditure)Purchases of property, plant and equipment of US$451.3 million (about double the previous year's US$231.0 million). The 10-K says capacity is being added both internally and at contract manufacturersSourced
Money (outside funding)NVIDIA subscribed US$2 billion of convertible preferred stock (2 March 2026). The joint release says the money will support R&D, future capacity and operations as the company builds out U.S.-based manufacturing in a new fab. Separately, convertible notes due 2032 raised net proceeds of US$1,254.7 millionSourced
Plants and sitesMain manufacturing locations are in the United States, Thailand, China, the United Kingdom, Slovenia and Japan. In July 2024 it bought the land and building of its Sagamihara wafer fab for US$42.2 million, and in March 2026 it bought a plant in Greensboro, North Carolina, for US$38 millionSourced
Outside investments, acquisitions and JVsAcquisitions: Oclaro (2018), NeoPhotonics and IPG Photonics' telecom transmission product lines (2022), and Cloud Light (2023). The 10-K says nothing about equity stakes in other companies or joint venturesAcquisitions sourced / stakes and JVs could not be confirmed
Size and location of the new fabThe joint release with NVIDIA says the company is "investing in a new fabrication facility", but the amount, location and start date have not been publishedNot disclosed
Universities, research institutes and public fundingThe only link the 10-K describes is partnering with universities for its internship programme. It mentions no joint research agreements and no public grants such as CHIPS Act funding or NEDO (Japan's state technology funding agency) awardsCould not be confirmed
A materials engineer's view: why making its own laser chips is a strength

Among the costs of an optical transceiver, the light-emitting device (an EML or DFB laser) is the part that is hardest to substitute. Crystal growth of InP (indium phosphide), forming the diffraction grating, facet coating and, above all, the yield (how many good devices come off each wafer) directly determine both supply capacity and cost. Assembly can be sent out to contract manufacturers, but epitaxial growth and wafer processing cannot easily be outsourced.

Explaining why gross margin rose from 28.0% to 41.7% in the year to June 2026, the company says approximately 54% of the gross margin dollar increase was driven by lower manufacturing costs as a percentage of revenue, "primarily due to higher internal factory utilization" Sourced. Wafer fabs carry heavy fixed costs, so margins improve sharply as utilisation rises. The same structure works in reverse: if demand falls, margins drop just as fast. The 18.5% of the year to June 2024 is the flip side. The 10-K also names China's restrictions on exports of indium and gallium as a risk.

In the 10-K the company writes that demand "is outpacing our current supply which has required us to make decisions on supply allocation" Sourced. For now, then, its plans are weighted as much towards increasing how much it can make as towards launching new products. It also states that it is investing in manufacturing capacity both internally and with contract manufacturers.

What could not be confirmed

None of the following appears in the 10-K, the 8-K or the official releases Not yet confirmed.

The location, investment amount and start date of the new U.S. fab / whether the Greensboro plant is that new fab / the exact amount and term of NVIDIA's purchase commitment (the release says only "multi-billion") / the names of customers A and B / capacity and revenue outlook for OCS and CPO lasers / market share by product. Figures of the "Lumentum has an X% share" kind are research-firm estimates, and this article does not use them.

8. What the company is aiming for in optical communications and photonics

This section includes things the company does not say directly. We set them out as inferences within what the primary sources support, with the evidence for each.

What the evidence suggestsPrimary information it rests onCategory
It wants to extend optics from outside the rack (scale-out) to inside the rack (scale-up)In the results release the CEO called these "the first signs that optics are starting to penetrate in-rack connectivity", and at ECOC it announced external light sources for CPO/NPO and die-to-die optical linksInference
It is going after the part that survives in the CPO era: the external light sourceThe ELSFP release presents the external laser source as something that "separates the laser from the highest-temperature environment" and can be "serviced, or replaced independently", and states that the UHP laser platform is "already in production"Inference
The NVIDIA relationship is closer to a long-term supply guarantee than an ordinary customer-supplier relationshipBesides the equity investment, the agreement includes a "purchase commitment" and "future capacity access rights". The agreement is non-exclusive, howeverInference
It is moving towards more manufacturing in the United StatesThe uses of NVIDIA's money explicitly include U.S.-based manufacturing in a new fab, and the Greensboro plant was bought the same monthInference
In transceivers, making its own lasers is its main point of differentiationThe 10-K lists "cost leadership and functional and vertical integration" in its strategy and says higher utilisation of its own fabs was the biggest driver of the margin improvementSourced
It wants the optical circuit switch to be its next pillarThe 10-K lists OCS among its R&D priorities, booked more than US$90 million of initial revenue in the year to June 2026 and states that manufacturing will expandInference
One inference in more detail: why the external light source?

CPO (co-packaged optics) places the optical engine right next to the switch or GPU package. Shorter electrical paths cut power consumption, but the optical transceiver disappears as a separate product, which is a threat to the companies that have made their living selling transceivers. Lasers, though, are sensitive to heat and have finite lifetimes, so designs that keep only the laser outside and make it replaceable are widely considered even for CPO. That is exactly what Lumentum stressed in its September 2026 release: an external laser source "separates the laser from the highest-temperature environment, while a pluggable ELSFP module can be accessed, serviced, or replaced independently of the compute or switching package" Sourced. Whatever shape the transceiver takes, demand for the light source remains. For a company that makes its own laser chips, we read this as the most natural ground to stake out Not yet confirmed. Our explainers on co-packaged optics and on NPO and LPO also discuss the role of the external light source.

9. Partnership map

Fig. 2 Lumentum's relationships in optical communications and photonics. Sources: Form 10-K for the year to June 2026, the Form 8-K filed on 2 March 2026 with the joint release with NVIDIA, and the two official releases of 21 September 2026. The NVIDIA agreement is non-exclusive, and combines an equity investment (convertible preferred stock) with a purchase commitment and capacity access rights. The relationship with Qualcomm and Corning is a joint demonstration at a trade show, not an announced co-development or supply agreement, so it is drawn dotted. The OCI MSA is an industry specification group; Lumentum writes that the ELSFP's optical interface is "designed to meet the applicable requirements" (it does not claim formal certification). Customers A and B account for 26.6% and 15.0% of revenue, but their names are not disclosed. The 10-K likewise describes the seller of the Greensboro plant only as a "third party", without naming it.

10. Technologies, products and services

The 10-K describes its products in two segments, "Components" and "Systems". We focus on those relevant to optical communications. For performance figures, we state whether the product is in volume production or a demonstration.

SegmentProductWhat it is and its status
ComponentsHigh-speed laser chips and laser assembliesThe light-emitting devices inside optical transceivers. They accounted for 78% of Components revenue growth in the year to June 2026, and the shift to 200G-per-lane products also lifted average selling prices (in volume production)
ComponentsUltra-high-power (UHP) lasersLasers for external light sources in CPO and NPO. The ELSFP release states that the platform is "already in production"
ComponentsCoherent components and narrow-linewidth lasersFor coherent transmission between data centres and over long distances. Supplied both to its own transceivers and to other companies (in volume production)
ComponentsSubsystems for telecom networksLine subsystems for long-haul terrestrial networks and pump products for undersea cables (the 10-K's wording is "charge pump products"), among others (in volume production)
SystemsOptical transceivers for the cloudRevenue up more than 173% in the year to June 2026. The CEO says the company is advancing adoption of 1.6T (in volume production)
SystemsOptical circuit switch (OCS)Switches between optical fibres while keeping signals as light. Initial shipments brought in more than US$90 million in the year to June 2026. The "OCS R300" product was exhibited at ECOC
SystemsROADMs, optical amplifiers, tunable transceiversDWDM equipment for carriers and network equipment makers (in volume production)
In developmentDWDM ELSFP laser moduleEight wavelengths (two four-channel bands centred near 1311 nm and 1331 nm). Wavelength accuracy of ±0.2 nm is a design target; up to 24 dBm (about 250 mW) per wavelength has been demonstrated; power consumption about 12 W. Initial availability expected in the first half of 2027
DemonstrationDie-to-die optical links with 1060 nm VCSELsA proof of concept combining Qualcomm's die-to-die interface and Corning's multimode fibre. 32 Gb/s NRZ per channel, an optical engine with about 10 Tb/s of aggregate transmit and receive capacity, and a design bandwidth density of about 1 Tb/s/mm
A materials engineer's view: what it means to turn a 3D sensing volume base to optical interconnect

What stands out in the 1060 nm VCSEL release is its explicit statement that the platform is "built on Lumentum's ultra-high-volume 3D sensing manufacturing base" Sourced. The VCSELs used for face recognition in smartphones are surface-emitting lasers: a single wafer yields huge numbers of devices, and they can be tested while still on the wafer. They are made in a fundamentally different way from edge-emitting EMLs and DFB lasers, and they lend themselves to two-dimensional arrays. In die-to-die optical links, what matters is less the speed of each lane than the number of lanes (the degree of parallelism) and the bandwidth per unit area, so this property pays off directly.

On the other hand, 1060 nm is neither of the wavelengths that dominate data centres today, 850 nm (multimode) and 1310 nm (single-mode). A new ecosystem has to be built, including the fibre, connectors and photodetectors that go with it, and we read that as the reason Corning's fibre and Qualcomm's interface were shown side by side in the same demonstration Not yet confirmed. Note that the demonstration is a proof of concept running at 32 Gb/s NRZ, and no date has been given for a product.

11. The risks this company carries

RiskDetailsCategory
Customer concentrationIn the year to June 2026, customer A accounted for 26.6% of revenue and customer B for 15.0%, more than 40% between them. The 10-K states that it has no long-term volume commitments with many of its customersSourced
Not enough capacityDemand is outpacing supply and the company is making supply allocation decisions. If capacity expansion falls behind, it will miss ordersSourced
Export controls on critical mineralsThe 10-K names China's restrictions on exports of indium, gallium, germanium and other materials as a riskSourced
Tariffs and export controlsTariffs between the United States and China, Thailand and other countries. Its main manufacturing sites and contract manufacturers are in Thailand, China and elsewhereSourced
Volatile marginsGross margin went from 18.5% (year to June 2024) to 41.7% (year to June 2026). It depends heavily on the utilisation of its own fabs and would move the other way if demand fellSourced
Equity ties with one customerNVIDIA has invested through convertible preferred stock. The agreement is non-exclusive, but it could affect relationships with other customersInference
Product mix change driven by CPOOnce optical engines move into the package, demand for stand-alone transceivers may fall. Whether external light sources can make up the difference is unknownInference
Share dilutionAbout 10.6 million shares were issued to convert notes into equity, and NVIDIA's preferred stock can be converted into common stock one for oneSourced
