Bistable Characteristics of an Ultrathin Metal-Dielectric Metasurface with a Nonlinear Element in Wood’s Anomalies

We propose and report on the design of a 1-D thin metallo-dielectric grating with Kerr type nonlinear element. In this paper, resonant lattice modes were observed while varying the frequency parameter to study the unique electromagnetic modes generated by Wood's anomalies. These mode resonances give rise to the enhancement of local field and nonlinear processes on Kerr type nonlinear element. The bistable transmission of the wave through the bar grating with nonlinear element was obtained.
