Transmission Characteristics Of The Electrooptically Perturbated Planar Dielectric Waveguide

Abstract

The theoretical investigation of planar dielectric waveeixide affected by electric field is presented herein. The electric field modifies refractive index of the 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 was assumed and calculation of transmission characteristics for TE and TM modes with the Y -cut lithium niobiate plate was done. As a conclusion, some practical applications of electrooptically perturbated waveguide are discussed.
