Rhea-AI Summary

Coherent (COHR) launched its PhotonLink™ integrated optics platform for next-generation AI datacenters on September 21, 2026.

The platform combines Coherent’s photonics portfolio and end-to-end assembly and test to support co-packaged optics (CPO), near-packaged optics (NPO) and emerging chip-to-chip connectivity. PhotonLink covers four optical functions—Generate, Shape, Guide and Receive—integrating InP lasers, VCSEL arrays, silicon photonics, isolators, specialty fibers, micro-optics and detectors into tailored optical modules. Coherent has more than ten CPO and more than ten NPO customer engagements, with anchor customers and long-term agreements, and over five chip-to-chip engagements. Revenue from PhotonLink is expected to begin ramping in Q4 CY2026, supported by a datacenter manufacturing base that has shipped over 300 million InP lasers and over one billion InP and GaAs photodetectors, and by expanded 6-inch InP and specialty fiber capacity.

Key Terms

co-packaged optics, indium phosphide, vertical-cavity surface-emitting laser, silicon photonics

4 terms

co-packaged optics technical

"The platform supports co-packaged optics (CPO), near-packaged optics (NPO)"

Co-packaged optics are optical components—lasers and fiber interfaces—physically packaged together with a network switch’s main processing chip so light-based data links sit much closer to the chip instead of traveling over long electrical traces. For investors, this matters because it can dramatically cut power use, boost data speed and density, and lower system costs in large data centers and telecom equipment, much like moving a power outlet next to a heavy appliance to avoid long, inefficient extension cords.

indium phosphide technical

"The portfolio includes indium phosphide (InP) lasers"

Indium phosphide is a high-performance semiconductor material used to make chips, lasers and detectors that carry and process light and very fast electrical signals. Think of it as a specialized road surface designed for high-speed light traffic—better suited than ordinary silicon for fiber-optic communications, high-frequency electronics and some sensors. Investors care because demand and supply for this material affect companies in telecom, data centers, photonics and semiconductor supply chains, influencing costs, production capacity and technology competitiveness.

vertical-cavity surface-emitting laser technical

"vertical-cavity surface-emitting laser (VCSEL) arrays"

A vertical-cavity surface-emitting laser (VCSEL) is a small semiconductor laser that emits light perpendicular to the chip surface, unlike traditional edge-emitting lasers that emit from the side. Think of it as a tiny flashlight built into a flat microchip, prized for low power use, easy manufacturing in arrays, and precise light control. Investors care because VCSELs enable technologies like optical data links, sensors, and consumer electronics, affecting companies' product capabilities and cost structures.

silicon photonics technical

"The portfolio includes indium phosphide (InP) lasers, vertical-cavity"

Silicon photonics is the technology that uses tiny structures etched into silicon chips to generate, control and detect light for moving data and sensing, essentially putting optical fiber functions onto a computer chip. For investors, it matters because it can dramatically increase data speed and energy efficiency in data centers, telecom networks and advanced sensors, potentially lowering costs and enabling new products much like replacing many metal wires with faster, low-power optical highways.

Combines critical photonics technologies with end-to-end assembly and test to deliver complete optical solutions for next-generation datacenters

SAXONBURG, Pa., Sept. 21, 2026 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), the global leader in photonics, today announced PhotonLink™, an integrated optics platform that brings together Coherent’s broad portfolio of critical photonics technologies, precision assembly and test capabilities to deliver complete optical solutions for next-generation AI datacenters. The platform supports co-packaged optics (CPO), near-packaged optics (NPO) and emerging chip to chip connectivity.

As AI systems continue to scale, demand for higher bandwidth and lower power is driving optical connectivity closer to compute and switching silicon. These architectures require lasers, silicon photonics, precision optics, fibers and detectors to work together. PhotonLink brings those technologies and the expertise to integrate them into one platform.

“The next leap in AI requires more than faster chips – it requires a new way to connect them,” said Jim Anderson, Chief Executive Officer at Coherent. “Customers need complete optical solutions, not just individual components. Coherent is uniquely positioned to bring together the critical technologies, integrate and test the finished assemblies, and manufacture them at scale. PhotonLink puts that capability to work for the next generation of AI infrastructure.”

Coherent’s vertical integration spans compound semiconductor materials, lasers, optics and specialty fiber through final assembly and test. PhotonLink gives customers access to both individual components and complete optical assemblies from one partner, helping simplify system design, streamline qualification and reduce the complexity of integrating technologies from multiple suppliers.

FROM CRITICAL TECHNOLOGIES TO COMPLETE OPTICAL ASSEMBLIES

The PhotonLink platform spans four functions of the optical path: Generate, Shape, Guide and Receive. The portfolio includes indium phosphide (InP) lasers, vertical-cavity surface-emitting laser (VCSEL) arrays, silicon photonics, isolators, specialty fibers, micro-optics and detectors. Coherent integrates these technologies into external laser sources, precision fiber assemblies and optical modules tailored to customer architectures.

CUSTOMER ENGAGEMENT AND MANUFACTURING SCALE

Coherent has more than ten CPO customer engagements and more than ten NPO engagements, with anchor customers and long-term agreements secured for both architectures. The company also has more than five engagements in emerging chip to chip connectivity. Revenue from the PhotonLink platform is expected to begin ramping in Q4 of CY2026.

PhotonLink builds on Coherent’s established datacenter manufacturing base, which has shipped more than 300 million InP lasers and more than one billion InP and gallium arsenide (GaAs) photodetectors. Coherent is expanding its 6” InP and specialty fiber manufacturing capacity to support the PhotonLink ramp.
