Ayar Labs Tech Stack

Co-packaged optical I/O chiplets for AI scale-up interconnect

Computer Hardware Manufacturing San Jose, California 51–200 employees Founded 2015 Privately Held
ayarlabs.com LinkedIn

Ayar Labs builds silicon photonics chiplets that move data optically between AI processors, targeting the bandwidth and power limits of electrical interconnect. Its stack is pure chip development: SystemVerilog/UVM verification on Xcelium and Questa, Cadence Virtuoso and Spectre for analog design, plus SerDes and RISC-V. Accelerating, overwhelmingly senior-to-principal engineering hiring alongside manufacturing-ramp projects points to a shift from R&D toward mass production.
