Bain Capital VenturesMeritechLumilens designs photonic interconnects meant to replace the copper wiring that currently links GPUs inside AI data centers, since electrical signals over copper only travel about a meter and a half at the data rates modern AI training requires. Its LumiCore platform combines silicon photonics, mixed-signal chips and electrical-optical interposers into a single architecture that supports pluggable transceivers as well as near- and co-packaged optics.
Based in San Jose, California, Lumilens emerged from stealth in August 2026, just two years after being founded, already shipping its first products into production hyperscaler data centers under a multi-billion-dollar customer agreement. The company owns its own manufacturing process, automation and test equipment, which it says gives it an edge in high-volume production.
