Light plays a critical role in enabling 21st century quantum information applications. Limited by size, engineers need to miniaturize quantum devices, which requires re-thinking certain components for harnessing light. Researchers have designed a simple, compact photonic circuit that uses sound waves to rein in light. The team’s measurements show that their approach to isolation currently outperforms all previous on-chip alternatives and is optimized for compatibility with atom-based sensors.
