Electro-optic Effect

Introduction

The electrooptic effect is the modification of the refractive index by an externally applied electrostatic field. In the linear electrooptic effect, the size of the perturbation to the refractive index is directly proportional to the strength of the local electrostatic field. In OptiBPM, there are two features to model in the linear electrooptic effect; one is…

Index Ellipsoid

In the absence of electrode fields the refractive index ellipsoid, or indicatrix, is of the following form: where no , ne  are the ordinary and extraordinary refractive indices, respectively. Under the influence of an electric field the index ellipsoid is deformed in space: In different cases of the cut, the propagation and polarization, and the…
