1304 A study on structural design of anisotropic optical multilayer coatings : Optimization of film thicknesses and materials

Abstract

Optical multilayer thin films are used for many optical devices for generating various specific filter function. Design of high performance optical multilayer thin films and cost saving are expected by using anisotropic materials in the multi-layer structure. Uniaxial optical anisotropic multilayer thin films are optimized to satisfy the design specifications by genetic algorithms in this study. Optimization program is developed for simultaneous optimization of number of layers, film thickness, refractive index and direction of director in each film. Some results of optimum design are reported.
