Abstract

In this work we performed an analysis, in Jones matrix formalism, of the temporal evolution and the of harmonic structure of the light modulated by transverse electrooptic effect in a modulator with two ADP crystals and a half wave plate placed between them, for an arbitrary bias voltage applied to the ADP crystals. The most important cases for applications, no bias voltage and quarter-wave plate bias voltage applied to the ADP crystals, are particularized. The spectrum of the modulator output intensity is presented both theoretically and experimentally..
