Optical interconnects (co-packaged optics) for large-scale AI compute fabrics and data centers
Ayar Labs builds in-package optical interconnects — TeraPHY chiplets paired with the SuperNova multi-wavelength laser — that move data between AI accelerators via light rather than copper, removing the bandwidth and power bottlenecks that constrain large-scale AI training and inference fabrics. Spun out of MIT/Berkeley research in 2015, the company crossed the unicorn threshold in December 2024 with a $155M Series D led by Advent International and Light Street Capital, with strategic participation from AMD, Intel Capital, and NVIDIA — an unusual three-way endorsement from the biggest accelerator vendors. Total funding stands at roughly $370M.
