Paper Abstract

In this communication we present our results on characterization of selected liquid crystalline materials in terms of their optical properties and their prospective applications as waveguiding layers in the integrated optic systems. Specifically, LCs refractive indices, with their dependence on temperature and within specific spectral range, have been measured and reported. The measurements were performed with use of the wedge-cell method. This simple goniometric technique is particularly useful when applied for liquid crystalline materials characterized by high refractive indices, for which refractometric methods are approaching their upper limits. It is important that the method proposed here requires relatively small amount of liquid crystalline material and gives reasonable results even if the light sources from the wide spectral range are applied. Experimental data allows for chromatic dispersion curves to be obtained by the numerical fitting with use of the Cauchy model.
