Abstract

A Faraday-Fabry-Perot (FFP) cavity, composed of an Fabry-Perot (FP) cavity and a piece of Faraday magneto-optical material, is presented. The principle of FFP cavity and its polarization modulation effect are described by use of optical matrix analysis. The result shows that the Faraday rotation is able to be magnified by more than two orders of magnitude in resonant FFP cavity, while different elliptically polarized lights are obtained in non-resonant cavity. Furthermore two novel applications, that is, optical isolator based on passive FFP cavity (FOI) and Faraday-Zeeman dual-frequency laser (FZDL) based on active FFP cavity whose eigen modes operate as circularly polarized lights and whose frequency difference can be adjusted continuously by magnetic field, are introduced. The principles, typical parameters and performance characteristics are analyzed in both applications.
