Recently, a new photopolymerization system for writing visible light initiated thiol-ene based H-PDLC Bragg reflection gratings was developed. Using this new method, Bragg reflection gratings were written with notch wavelengths out into the NIR. The aim of the present work is to determine the grating parameters like spacing, LC width, polymer width and droplet density from morphological studies and compare with those obtained from optical measurements. The electro-optical performance of ...
