LOCALLY NONLINEAR PLANAR WAVE-GUIDE WITH GIROTROPY

In the paper, some results concerning light propagation in a planar wa veguide with a local nonlinearity are presented. External magnetic fie ld is assumed as a source of girotropy. A strong laser beam perpendicu lar to the film couples with the transmitted wave via the nonlinear me dium. Both fields influence the outgoing wave leading to some essentia l changes in its polarization. The parameters characterizing this pola rization have been calculated and discussed for several interesting re slizations.
