Paper Abstract

In this work we present theoretical and experimental results of influence of electric field on reorientational nonlinearity in homeotropic oriented nematics. In the analyzed configuration the light beam passing through the liquid crystalline layer induces the reorientation, which is observed in far-field diffraction pattern changes as a result of self-modulation effect. The created phase mask inside the nematic cell can be used in optical switching or to control the propagating direction of optical signals passing through the liquid crystalline cell. Both electric and optical field control the observed phase pattern dynamics. The response time in reorientational phenomena is large and its determination and reducing is very important issue for applications. Obtained results are in good agreement with theoretical prediction.
