Coherent Corp. stock gained 4.82% to $332.66 as the company introduced new optical technologies for expanding AI infrastructure. The shares recovered from an early decline and reached an intraday high during Monday trading. Meanwhile, Coherent outlined new products ahead of the ECOC 2026 conference in Málaga, Spain.
Coherent plans to demonstrate technologies covering datacenter connectivity, optical transport, advanced materials, specialty fibers, and thermal management. The company will also highlight solutions for co-packaged and near-packaged optical systems. These technologies address rising bandwidth and power requirements across large computing networks.
Meanwhile, Coherent introduced PhotonLink, an integrated optics platform supporting advanced packaged optics and chip-to-chip connections. The platform combines optical components, assemblies, integration capabilities, and large-scale manufacturing. Therefore, Coherent aims to provide customers with a broader portfolio for building high-density computing infrastructure.
The company operates across materials, devices, modules, components, and optical systems for networking markets. This vertical structure allows Coherent to combine several technologies within complete connectivity products. Its expanded portfolio also targets network links inside datacenters and connections between separate facilities.
Coherent will demonstrate a 6.4T near-packaged optical engine for high-density scale-up and scale-out networks. The engine combines silicon photonics, fiber attachment technology, external laser sources, and Coherent laser components. Consequently, the design targets greater capacity while addressing space and power constraints.
Coherent will also demonstrate a compact 3.2T transceiver using two 1.6T optical paths. The OSFP-sized design includes eight 425G PAM4 optical lanes alongside Coherent emitters and photodiodes. This architecture highlights development toward next-generation 400G-per-lane optical connectivity.
Coherent will showcase high-density VCSEL and photodiode arrays for highly parallel optical architectures. These components target low-latency connections used within packaged optical systems. The company will also present specialty fibers designed for improved coupling and higher-density datacenter connections.
Coherent will present its LS200 full C-band pluggable optical line system for datacenter interconnect applications. The architecture places optical transport functions closer to network routers and switches. Furthermore, it supports flexible point-to-point connections between datacenters handling growing computing workloads.
Another pluggable system supports 800G digital coherent optics and as many as 32 DWDM wavelengths. The system can carry up to 25.6Tbps across distances ranging from two to 200 kilometers. Coherent designed the compact system to increase transport capacity while reducing equipment requirements.
Coherent will also showcase advanced thermal materials designed for infrastructure facing higher power density and cooling requirements. Diamond-based materials form part of the company’s approach to managing heat from increasingly dense computing systems. Together, these optical and thermal technologies expand Coherent’s exposure to continued spending on high-capacity AI infrastructure.
