Investigation of parameters of the multimode four-layer waveguide structures and their influence on the light propagation

Elżbieta Auguściuk, Grzegorz Biniecki


In the paper investigation of multimode four-layer waveguide structures by modified m-line spectroscopy method was presented. Waveguide layers with a gradient profile of the refractive index were prepared by the ion-exchange method. Dielectric layers were deposited on the waveguide by the spin-coating method. The investigation was aimed at learning the influence of parameters of the waveguide layer and the thin layer deposited on the waveguide on the propagation of light in this waveguide.
