Abstract

We describe how photon-phonon interactions can be used to achieve large optical non-reciprocity and ideal optical isolation with integrated photonics. Our experiments rely on breaking time-reversal symmetry within dielectrics (e.g. silica, aluminum nitride, lithium niobate) using the Brillouin scattering nonlinearity. We show how the breaking of time-reversal symmetry can also be used to suppress disorder-induced backscattering in optical resonators.
