EXPERIMENTAL RESULTS ON THE LIGHT-PROPAGATION IN A NONLINEAR WAVE-GUIDE WITH NEMATIC LIQUID-CRYSTAL - HYBRID ALIGNMENT CASE

The light propagation in a LC nonlinear planar waveguide is studied fo r both TE and TM polarization states of incident light. Two different nematic liquid crystal samples were employed with hybrid alignment in a special guiding structure ad hoc realized for this work. The experim ental results show that the guided modes are affected by the incident light power. In particular, the power exchange of the propagating ligh t between different modes was studied in detail.
