Paper Abstract

Analysis of electromagnetic field transmission in planar waveguide affected by electric field is presented herein. The electric field modifies rafractive index of waveguide only by means of Pockels effect. As a result, distorted waveguide causes radiation losses for guided electromagnetic waves in different way for TE and TM modes. The model of step index waveguide with Y-cut lithium niobate substrate was assumed and calculation of transmission characteristics for TE and TM modes was done. Next some results of experiments with propagation of TE and TM modes in direction X for electrooptical perturbated lithium niobate diffused titanium (Ti:LiNb03) planar waveguide are presented.
