Abstract

The principles of realization of solid-state optical modulators for building fiber-optic sensors are considered in the article. The electro-optical effect used by many optical modulators is described. Detailed volume modulators based on electro-optical and acousto-optic effects are presented. Integral-optical modulators with phase and interferometric intensity modulation, as well as pure-fiber optical modulators with phase modulation are described with description. Modulator models in the form of equivalent circuits with lumped parameters and methods for obtaining the frequency characteristics of optical modulators. The implementation of a fiber-optic frequency converter is presented, in which an acoustic wave from a sensor element perturbs two channeled modes in a fiber.
