Analysis of polarized light in multilayers

Through the extension of the matrix formalism the dispersion properties of multilayered waveguides for TE and TM modes are expressed in simple formulas. The considerations of waveguiding are investigated in isotropic absorbing and nonabsorbing film systems. The influence of position, thickness and absorption of the central thin film on the propagation of the light in five layered planar waveguides are analyzed in detail. When the central metallic absorbing film is located in the middle of the structure the expressive suppressing of guided modes of the even orders in perceptible. The results show that the guided mode tuning effect can be realized with nonabsorbing structure. The important dependence of effective refraction indices of the guided modes on the central film thickness has been observed.
