Fig. 2: Nonlinear tuning of the optical response of metasurface.
From: All-optical modulation of quantum states by nonlinear metasurface
a Numerically simulated transmission T for V- and H-polarizations are given by red and blue lines, respectively. The anisotropic response is further characterized by the transmission ratio (\(T_V/T_H\), the vertical coordinate is in log scale) and the relative transmittance phase difference ϕ between the orthogonal polarizations. Solid lines present results for metasurface without control light, and dashed lines are those under the control light. b Experimental results of T, \(T_V/T_H\), and ϕ. The wavelength of photonic quanta is 808 nm, which is represented by vertical black dashed lines
