Abstract

The role of surface effects and their contribution to reorientation in the two-beam coupling process on structures containing liquid crystals and photoconducting polymer layers was investigated. It was found that surface charge layers could be discharged in bright areas and led to reorientation and spatially modulated Freedericksz transition. A high two-beam coupling gain was observed when the reorientation grating is π/2 phase shifted from the interference pattern. It was stated that the process of buildup and discharge of surface charge layer was responsible two-beam coupling gain.
