Uma ferramenta educacional para o estudo do efeito de Pockels e sua aplicação em moduladores ópticos.

Abstract

In the study of electrooptic interactions with matter, the linear electrooptic effect or Pockels effect and its applications as light amplitude and phase modulators represent fundamental topics to be understood. With this in mind, this research project aims at proposing an education tool to ease the comprehension of such effect. This report firstly provides a theoretical background, which concerns the concept of index ellipsoid as well as of the Pockels effect. In the following, the applications of such effect are presented in the form of amplitude, longitudinal and transverse, and phase optical modulators. All the mathematics regarding the modulators are also presented. Finally, the proposed computer learning tool is presented. Its use can be divided into two sections, which are: The study of the Pockels effect and the study of its applications. For both sections, optic crystals composed of different materials have been used, which allows the user to perform a visual comparative study.
