Abstract

The collected results of the refraction index profile measurement in highly anisotropic, tunable liquid crystalline waveguides are presented. The three different liquid crystal substances have been examined. Initial orientation of the liquid crystal layer is deformed by an external electric field. The initial orientations have been prepared as twisted and planar for liquid crystal material with positive dielectric anisotropy. In the liquid crystal material with negative dielectric anisotropy as initial has been examined hybrid orientation.
