Abstract

We demonstrate nonreciprocal one-way transmission through a half-a-micron-thick nonlinear silicon-VO₂ metasurface for low-power CW excitation. Reciprocity is broken by optically self-induced phase transition of VO₂ occurring at different intensities for the opposite directions of illumination.
