Ayar Labs is a startup specializing in co-packaged optics (CPO) hardware. Their technology transmits data packets in the form of light, offering higher bandwidth and lower power consumption compared to traditional copper-based interconnects. Their key components include SuperNova, a light emitter chip, and TeraPHY, a chip that encodes data into light using miniaturized optical devices like microring resonators. TeraPHY supports the UCIe standard, allowing direct integration with processors like GPUs, and boasts high traffic processing capabilities with reduced latency.
