Meet Lumilens

Lumilens is a San Jose-based photonics company building optical interconnect infrastructure for large AI data centers. Its LumiCore platform combines in-house silicon photonics, mixed-signal ICs, electrical-optical interposers and optical systems to power pluggable transceivers, near-package optics and co-packaged optics. These products address scale-out networking between racks and scale-up connectivity between GPUs, where copper links face bandwidth and distance limits. Lumilens also develops proprietary manufacturing processes, robotics and automated testing for high-volume optical production. The company emerged from stealth in 2026 and is already shipping its first scale-out product into a hyperscaler's production AI data centers under a multi-billion-dollar customer agreement.View more
