At Ayar Labs we’re about to revolutionize computing by moving data with light. We’re unleashing processing power for artificial intelligence, high performance computing, cloud and telecommunications by removing the bottlenecks created by today’s electrical I/O – making it possible to continue scaling computing system performance. Ayar Labs is the first to deliver an optical I/O solution that combines in‑package optical I/O chiplets and multi‑wavelength remote light sources to replace traditional electrical I/O.

This silicon photonics‑based I/O solution enables chips to communicate with each other from millimeters to kilometers, delivering orders of magnitude improvements in latency, bandwidth density, and power consumption.

With our strong collaborations with industry leaders and government, our deep ties to MIT and UC Berkeley, and our commitment to hiring the best engineers in photonics and electronics, joining our team gives you the opportunity to collaborate with renowned experts on challenging, paradigm‑shifting work.
