Tower Semiconductor ( TSEM ) stock is among today’s top performers. What’s fueling TSEM momentum?

Tower, Coherent Demonstrate 400 Gbps Per Lane Silicon Photonics Breakthrough

The companies said they successfully demonstrated 400 Gbps per lane data transmission using a silicon modulator built in a production-ready silicon photonics, or SiPho, process. According to the announcement, the demonstration showed a clear open eye at 420 Gb/s PAM4 and used Coherent's InP CW high-power laser.

Tower said the achievement is aimed at enabling next-generation 3.2 terabit optical transceivers and expanding the use of silicon in pluggable transceivers and co-packaged optics for datacenter connections.

AI Datacenter Demand Drives Interest In Next-Generation Optical Interconnects

The news appears to be boosting investor sentiment because faster optical interconnect technology is increasingly critical as AI infrastructure demand accelerates. Tower and Coherent said the optical transceiver market continues to outpace prior projections, increasing the need for higher-bandwidth solutions across datacenter environments.

CEO Russell Ellwanger said the result could extend silicon's role for another generation of transceivers while allowing Tower to reuse large multi-fab capacity investments already in place.

Coherent CEO Jim Anderson added that the partnership is helping advance high-performance optical interconnects for AI-driven datacenters.
