2-WAVE REFLECTION AT A NONLINEAR INTERFACE

An analysis of two-wave reflection at a nonlinear interface is present ed. We consider the case of two monochromatic plane waves of different frequencies interacting with self-focusing and self-defocusing nonlin ear Kerr media. The influence of the cross-phase modulation effect on states of total and partial reflection of waves is examined. It is sho wn that those states change bistably or multistably and depend on the parameters of the incident waves and the type of boundary between the linear and the nonlinear media. We show that the intensity of one wave can control the state of reflection of the second wave and vice versa . (C) 1998 Optical Society of America.
