This project aims to create a new class of integrated microwave information processors on a single optical chip. Using electro-acoustic coupling in semiconductors, we expect to reduce optical power requirements one thousand-fold, enabling the emergence of practically deployable processors using ordinary telecom lasers. The
expected project outcomes are inexpensive, compact, stable and energy efficient microwave photonic processors, a key requirement for reference standards and precision measurements of time and frequency. This technology will create a multitude of opportunities for commercial development in the fields of defence, information security, autonomous vehicles, sensing, and ultra-high bandwidth mobile communications.
