Numerical experiments on the Fabry–Perot transmission resonances in spatially dispersive metal–dielectric multilayers

Abstract

We study the transmission of electromagnetic waves through regular metal–dielectric arrays, where the metal layers are spatially dispersive and the dielectric layers are media with Kerr-type nonlinearity. We develop an algorithm for determining the electromagnetic field distribution and show that the transmission spectra of multilayers can change significantly in the presence of even a relatively weak nonlinearity, resulting in multiple possible states of the transmitted electromagnetic field. Similarly, we report that spatial dispersion of metal layers leads to suppression of the nonlinear effects of the dielectric ones, reducing the possible number of different states of the transmitted electromagnetic field.
