Abstract
Modulation and switching of light waves in Yttrium iron garnet (YIG)–Gadolinium gallium garnet (GGG) waveguides using Farady rotation(1), and light propagation and mode-conversion in a thin-film dielectric waveguide using magnetooptic YIG substrate(2,3) had been studied in detail. More recently, propagation and mode-conversion in a YIG/GGG waveguide with an isotropic top layer using Faraday rotation was also analyzed.(4) In this paper we report on wideband modulation at multigigahertz (2 to 7 GHz) center frequency that results from planar magnetooptic diffraction by magnetostatic surface waves in the YIG/GGG waveguide.
