Non-reciprocal optical mirrors based on spatio-temporal acousto-optic modulation
Non-reciprocal optical mirrors based on spatio-temporal acousto-optic modulation
The recent surge of interest in temporal modulation schemes to induce magnet-free non-reciprocity has inspired several exciting opportunities for photonic technology. Here, we investigate a scheme to realize free-space isolators and highly non-reciprocal mirrors with weak modulation imparted by an acoustic wave. Conventional optical mirrors are reciprocal: in a given …
