Non-conservative optics with dielectric metasurfaces

Abstract

We introduce a general approach for tailored nonconservative transformations of polarization states of light based on scattering and interference from specially engineered nano-resonators in ultra-thin dielectric metasurfaces. We present theoretical and experimental results demonstrating the fundamentals aspects and potential applications of such metasurfaces. These include an optimal monitoring of deviations from a selected polarization, transformation of any input two-photon quantum polarization-entangled state to an arbitrary target state, and discrimination between a set of objects with different polarization characteristics.
