Light propagation along periodic metal-dielectric layers.
Analysis and experiments on TE and TM waves along periodically laminated metal-dielectric layers are described; the waves propagate parallel to the layers. Aluminum (Al) and silica (SiO2) are chosen as the metal and the dielectric, respectively. We find that the attenuation for TE waves is much higher than that for TM waves. Typically, alphaTE/alphaTM ranges from 10(3) to 10(4). Thus, an optical polarizer can be made in a multilayer structure.
