TM WAVES IN MAGNETOOPTIC-NONLINEAR WAVE-GUIDE

The TM waves guided by the linear thin film sandwiched between magneto optic semi-infinite substrate and nonlinear Kerr-type semi-infinite cl adding have been investigated theoretically and numerically. Both the dispersion relation and the guided power flow have been derived. The p ower flow dependence of the nonreciprocal behaviour of these waves is discussed. Introducing a nonlinear material into magnetooptic waveguid e structure leads to an interesting application for the new class of i ntegrated devices which combine magnetooptic and nonlinear effects.
