Abstract :
The TE-to-TM optical mode conversion that takes place when magnetostatic waves (MSW) and a guided light beam propagate collinearly in an yttrium-iron-garnet (YIG) film is investigated. The experimental results show unexpectedly high intensity and broad bandwidth when microwave power levels on the order of 35 dBm are used. This effect is clearly nonlinear, and it is speculated that it could be due to spin wave excitation or to high transducer current effects. The experiments were carried out between 4 and 7 GHz using 1.3-μm radiation
