Optical mode conversion in a ferrimagnetic film containing magnetostatic forward volume wave

This paper presents a general description of the mode coupling in the optical waveguide containing a magnetostatic forward volume wave(MSFVW). The power-conversion efficiency of TEI-TMm modes have been obtained for several kinds of 1/m, which are corresponding to the different center frequency. The multi-band modulator has been predicted and the advantage of modulation by MSFVW over MSSW has been discussed.
