$FN Fabrinet is a precision manufacturer that builds and assembles optical products for many of the big names in the industry. A simple way to think about it is that Fabrinet is one of the factories behind the optical boom. Growth is coming from higher volumes in telecom, cloud, and AI optics, with fiscal Q2 2026 revenue reaching a record $1.13 billion.
$LWLG
Lightwave Logic develops special polymer materials used in modulators, the components that switch light on and off inside a photonic chip. Faster, lower-power modulators can improve future optical links. The current growth story is early commercial progress, especially its new work with Tower to bring modulator designs into a silicon photonics process kit for 2026 tapeouts.
$LITE
Lumentum makes laser chips, optical components, and photonic products used inside transceivers, optical circuit switches, and newer optical architectures. It supplies several of the high-value light-generating parts that AI networks need. Growth is coming from strong cloud demand, 200G-per-lane components, a large optical switching backlog, and continued expansion into co-packaged optics.
$MTSI
MACOM makes high-speed analog and optical semiconductor parts, including photodiodes, laser-related components, and other chips that help optical links work properly. These are the supporting electronics and optical building blocks inside many modules and systems. Growth is coming from 800G and 1.6T deployments and from stronger data-center demand.
$MRVL
Marvell makes the DSP chips and other silicon that translate data between the electrical and optical worlds. These chips sit inside high-speed optical links and help them run at the speeds AI clusters require. Growth is coming from AI data-center infrastructure today and from its longer-term push into optical fabrics after the Celestial AI acquisition in the future.
$NOK
Nokia builds optical transport systems and networking platforms that connect data centers and telecom networks. After the Infinera acquisition, it has even more depth in optical chips and transport equipment for large-scale networks. Growth is coming from AI and cloud demand inside Optical Networks.
$POET
POET builds optical engines and packaging platforms that bring several optical functions together in one compact assembly. Packaging and alignment are major cost and complexity points in photonics manufacturing. Growth is tied to 800G optical engine shipments expected in the second half of 2026.
$SANM
Sanmina is a large electronics manufacturer that helps build servers, networking gear, and some optical hardware. The easiest way to place it in the stack is as an important manufacturing platform for AI infrastructure. Growth is coming from the broader AI hardware buildout, including the added scale from the ZT Systems manufacturing assets.
$SMTC
Semtech makes signal and interface chips that help optical modules send and receive data cleanly at very high speeds. These parts are important in 800G, 1.6T, and future 3.2T links because signal quality matters more as speeds rise. Growth is coming from data-center demand and from a broader optical product lineup.
$SIVE
Sivers develops photonics and wireless semiconductor products, including indium-phosphide-based optical devices. It sits closer to the chip layer of the stack, where specialized optical parts are created for communications and sensing. Growth is coming from a larger opportunity pipeline and improving product mix.
$TSEM
Tower is a foundry, which means other companies use its factories to make silicon photonics chips. Those chips are the brains on silicon inside many modern optical modules. Growth is coming from a surge in silicon photonics demand, with 2025 SiPho revenue reaching $228 million and large capacity expansions already being reserved years ahead.

$VIAV Viavi makes the testing tools used to check fiber links, optical modules, and AI networks. It helps customers prove that the hardware works before and after deployment. Growth is coming from heavier testing needs as speeds move toward 1.6T and as AI data-center networks become larger and more complex.
