About Ayar Labs
Ayar Labs makes optical input and output for chips. Its TeraPHY chiplet is a small silicon photonics die that sits in the same package as a processor and sends data as light, and its SuperNova is a separate multi-wavelength laser source that feeds light to those chiplets over standard single-mode fibre. This replaces electrical links, which lose energy and range at high speeds. The company was founded in 2015 and describes its chiplets as compatible with the UCIe chiplet standard. Directories place its headquarters in San Jose, California.
Ayar Labs was founded in 2015 and is based in Santa Clara, CA, United States. It is listed under Photonic Computing, Interconnect & Networking. Reported funding is $500M Series E (Mar 2026, led by Neuberger Berman; NVIDIA, AMD strategic).

What Ayar Labs works on
Photonic Computing
Photonic computing uses light instead of electricity to carry or process information. Photons have no charge, so light in a waveguide does not cause the resistive heating that current in a wire does, though lasers and modulators still use power, and many wavelengths can share one waveguide. The industry has two quite different parts: moving data with light, and computing with light.
Interconnect & Networking
Interconnect is the set of links that move data between chips, between boards and between racks. It includes wires on a package, cables inside a server, and the network switches and optical fibre across a data center. A processor is only as useful as the speed at which it can get data in and out.
