Nonlinearity-Induced Nonreciprocity in Passive Silicon Gratings Supporting Quasi-Bound States in the Continuum

Optical nonlinearities, combined with structural asymmetry, can break reciprocity and realize devices that transmit light asymmetrically. We show the first experimental implementation of this concept for free-space radiation, using silicon metasurfaces supporting asymmetric quasi-bound states.
