Abstract

Metallo-dielectric structures are used as optical filters whose transmission and reflection characteristics can be changed by varying the thicknesses of the metal and dielectric, and the number of layers. A first estimate of their performance can be found by using effective medium theory and Berreman analysis. Incorporation of an electro-optic material within a metallo-dielectric sandwich can enable electronic tuning of the structure through application of an external voltage. We analyze the performance of metallo-dielectric electro-optic sandwiches using effective medium theory for the metallo-dielectric multilayers and the transfer matrix method for the three-layered sandwich.
