Abstract

The use of polymer-dispersed liquid crystal films to fabricate gratings was made. The written gratings are permanent, but are electrical switchable. In this paper, we report the results obtained from the dynamical studies of gratings formed in PDLC films having various liquid crystal-polymer mixing ratios. The results showed that thermal grating dominated at early times. Later, it was offset or quenched by the photopolymerization effect which eventually dominated and determined the characteristics of the final grating.
