Determining the optical constants of vacuum evaporated II-VI compound thin films with optical waveguides

The optical constants of high-index II-VI compound thin films on low-index glass waveguides are determined from the concept of resonant thickness using the complex dispersion relation together with experimental properties of guided waves. The results are compared with the refractive indices of bulk crystals of II-VI compounds(CdS, ZnSe, ZnS,and ZnTe).
