First Silicon for Photonics Startup with DARPA Roots

Jan 29, 2019Media

Ayar Labs, a silicon photonics startup based in Emeryville, California, is getting set to tape out its electro-optical I/O chip, which will become the basis of its first commercial product. Known as TeraPHY, it’s designed to enable chip-to-chip communication at lightning speed. The company is promising bandwidth in excess of one terabit per second, while drawing just a tenth the power of conventional electrically-driven copper pins.

The problems of copper pins and electrical signaling encompasses power, data reach, and chip real estate limitations. As the performance of processors advance, faster data rates are required…
