ABSTRACT:
A Faraday rotator of multilayer film type is provided which can achieve excellent optical characteristics with a reduced number of layers. In the Faraday rotator, a metal reflection film, a periodic dielectric multilayer film made of silicon dioxide SiO2and tantalum pentoxide Ta2O5, a magneto-optical thin film, and another periodic dielectric multilayer film made of tantalum pentoxide Ta2O5and silicon dioxide SiO2is formed sequentially. Light incident on a polarizer goes therethrough, is reflected at the metal reflection film while traveling trough the periodic dielectric multilayer films, and goes through an analyzer to exit out.
