Photonic Integrated Circuits for Microwave Signal Processing

Quick fact

Photonic integrated circuits can process microwave signals with terahertz-level bandwidths—far beyond what electronic circuits can achieve—enabling speeds 1000 times faster than conventional electronics.

Why this is interesting

Your phone's microwave signals are running into a bottleneck, but what if we could process them using light? Photonic integrated circuits do exactly that, and they're smaller than a fingernail.
