Abstract

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.
