Abstract
Theoretical approach to the operation of a prism-waveguide coupler is presented. It has been shown that application of a suitable optical structure in the measurement device creates waveguide conditions for the investigated liquid-crystalline layer. Basing on this fact a measurement system for determining of propagation constants of waveguide modes has been proposed. Influence of the refractive index distribution in a layer as well as its thickness on the liquid-crystalline waveguides are presented and discussed. Investigation results for liquid crystalline layers, also these modified by influence of an electric field are also described.
