Phase-matching-free sensing with undetected light using a nonlinear thin-film metasurface

Abstract In this article, we report classical sensing with undetected light at a wavelength of 1500 nm, detected on a silicon camera at 580 nm, using four-wave mixing from a plasmonic metasurface. The bidirectional nonlinear scattering due to inherent reflections from such thin n...
