| Ayar Labs | Ayar Labs develops a monolithic in-package optical I/O (MIPO) solution for applications that require high bandwidth, low latency, and power-efficient short-reach interconnects.The company disrupts the traditional performance, cost, and efficiency curves of the semiconductor and computing industries by driving improvement in interconnectbandwidth density at lower power. Its 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’s flagship product is a chip called TeraPhy that implements its optical technology on compact silicon die. The chip can be integrated directly into a central processing unit, graphics card, or another processor to give it optical data transmission capabilities.The Emeryville, California-headquartered company was established in 2015 by Alex Wright-Gladstein, Vladimir Stojanovic, Chen Sun, and Mark Wade. | $155M | Series D | Dec 11, 2024 |  |
