Scientists Create Tiny Chip That Uses Light Instead of Electricity To Process Information

Monash University researchers built a nanoscale photonic valleytronic chip that processes information with light instead of electricity.

The chip combines signal generation, routing, and detection on one room-temperature integrated platform.

It uses the valley degree of freedom and metasurfaces to control quantum light signals.

The breakthrough could make light-based computing and communication faster, more energy efficient, and easier to deploy.
