Monash Scientists Build 1 Chip That Generates, Steers and Reads Light for AI Computing

Monash University researchers built a single chip that generates, routes and reads light-based signals, integrating functions that valleytronics devices had previously achieved only separately.
Room-temperature operation is a key advance: the chip uses atomically thin materials stacked with engineered metasurfaces to control light’s “valley” degree of freedom and convert those signals into electrical outputs.
Two images were encoded and processed simultaneously in a proof-of-concept test, showing the device can handle multiple information streams for faster, lower-energy data processing.
Published in Nature Photonics, the work points toward scalable photonic hardware for AI, quantum computing, secure communications and next-generation optical networks.
