Ayar Labs is a leader in silicon photonics for chip-to-chip connectivity designed for applications that require high bandwidth, low latency, and power-efficient short-reach interconnects.

Ayar is disrupting the traditional performance, cost, and efficiency curves of the semiconductor and computing industries by driving a 1000x improvement in interconnect bandwidth density at 10x lower power.

Ayar Labs was founded in 2015 by Mark Wade, Chen Sun, Vladimir Stojanovic, and Alex Wright-Gladstein. The company is headquartered in Emeryville, California, with an office in Santa Clara, California.

Ayar Labs’ patented approach uses industry standard cost-effective silicon processing techniques to develop high speed, high density, low power optical based interconnect “chiplets” and lasers to replace traditional electrical-based I/O.

Ayar offers TeraPHY, a Monolithic In-Package Optical I/O (MIPO I/O) solution that uses industry standard cost-effective silicon processing techniques to develop high speed, high density, low power optical based interconnect “chiplets”.

Ayar is ramping production and securing supply chain partners, as signaled by previously announced multi-year strategic collaborations with Lumentum and Macom, both leaders in optical and photonic products, as well as GlobalFoundries on its new GF Fotonix™ platform.

Ayar is backed by Intel Capital, Lockheed Martin Ventures, Founders Fund, Atreides Management, NVIDIA, Boardman Bay Capital Management, IAG Capital Partners, Hewlett Packard Pathfinder, Downing Ventures, BlueSky Capital, Applied Ventures, GlobalFoundries, Castor Ventures, Agave SPV, Capital TEN, VentureTech Alliance, and others. The company raised an additional $25M in Series C1 round on May 24, 2023, bringing its total Series C raise to $155M. The additional investment brings Ayar's all time funding to $219.5M to date.
