Headquartered in San Jose, CA, Ayar Labs builds co-packaged optics that move data between chips with light instead of copper, reducing power consumption while boosting bandwidth for AI infrastructure. Its flagship TeraPHY optical engine is manufactured in concert with leading semiconductor partners and is designed to slot directly into existing accelerator and switch designs. By replacing traditional electrical I/O with optical links, the technology delivers significant performance gains and cost savings in power-constrained environments. Following its latest financing, the company plans to ramp production and testing capacity, open and staff a new office in Hsinchu, Taiwan, and deepen ecosystem partnerships to speed customer deployments. Ayar Labs’ CPO solution is already qualified for industry-standard fab, manufacturing, and packaging flows, positioning it for broad adoption. The company has raised a cumulative $870 million to date, providing substantial capital to execute its global expansion and commercialization roadmap.
