Ayar Labs is pioneering co-packaged optics (CPO) for AI infrastructure, using light instead of electricity to move data between chips. We design our TeraPHY™ optical I/O chiplets and SuperNova™ light sources in-house and, as a fabless company, partner with leading manufacturers to build them. Our Thailand team works on site at Fabrinet, our contract manufacturing partner, as the Ayar Labs technical owners of the products Fabrinet builds for us.
