# Avicena Tech

> Avicena Tech builds LightBundle, a microLED-based optical interconnect that moves data between chips at terabit-per-second densities while sipping sub-picojoules of energy per bit. The Sunnyvale company is betting that the GPU clusters powering AI need a new physical layer - one that copper can't deliver and traditional silicon photonics can't match on power.

- **Founded:** 2019
- **Headquarters:** Sunnyvale, California, United States
- **Founders:** Bardia Pezeshki (Co-founder, CTO (former CEO)), Rob Kalman (Co-founder, Chief Scientist)
