Abstract(in English) This paper discusses optical interactions with magnetostatic waves propagating along microstrip and slot lines on the yttrium iron garnet (YIG) substrate both theoretically and experimentally. After estimating the dispersion curve of the stripline it shows the mixed status of quasi-TEM and magnetostatic forward volume wave modes through coupling between their two modes near magnetic resonance frequency. The experiments in optical interaction were carried out using 100 μm thick YIG film and laser beam of 1.3 μm wavelength, which was illuminated at a edge of YIG film. The modulation index of few percent due to interaction were observed at frequency of 3.2 GHz along with magnetic wall oscilation effect by quasi-TEM mode. Their results were compared to the coupled mode theory. The application of the devices is also briefly discussed.
