Modulators and Switches: Controlling Light With Light

Modulators are the valves of photonics — they encode data onto light, route signals, and switch beams. Excitons offer a way to make those valves smaller, faster, and operable at lower power by letting one beam of light control another.

Photonic AI Accelerators: Where Excitonic Devices Fit

Photonic chips already accelerate the linear math of neural networks. The hard part is the nonlinearity between layers — and that is where excitonic devices could earn their place.
