Temperature-Dependence of the Optical-Phase Shift in a Polymer-Dispersed Liquid-Crystal
We report a study of the temperature dependence of the optical phase shift induced by a polymer dispersed liquid crystal subjected to a low frequency electric field. In the framework of a recently introduced model we point out the role of two parameters strictly depending : on the PDLC configuration : an "effective elastic constant" K-d and a droplet "voltage-constant" V-d. We show that a suitable temperature dependence of such parameters is able to give a good agreement between experimental data and theoretical values.
