Research output: Chapter in Book/Report/Conference proceedingConference contribution


We demonstrate an unreleased acousto-optic frequency-shifting optical isolator on chip, that exhibits improved mechanical and thermal robustness compared to prior art. The system leverages traveling surface acoustic waves (SAW) to break the symmetry for light propagation via indirect intermodal scattering.
