Abstract :
We have observed experimentally the coupling effects between magnetostatic forward volume waves (MSFVW) and optical guided waves in a bismuth-doped yttrium iron garnet (BGYIG) film, and these effects were demonstrated in a short interaction length (5 mm). The detailed coupling mechanics existing between microwave frequency, high power and optical guided waves are not yet clear. This paper reports on optical-MSFVW interaction from an experimental view point. A microwave frequency range of S-band (2-4 GHz) was used to excite MSFVW in a Bi-YIG film. An optical wave with 1.152 μm wavelength was directly injected through the side wall of the Bi-YIG film
