Tunable polymer/liquid crystal composite devices

This thesis focused on developing new electro-optical devices based on PDLC or H-PDLC. In particular, we firstly optimized the fabrication conditions for H-PDLC Bragg gratings. Using holography, one-dimensional (1D) H-PDLC Bragg grating was fabricated. The 1D H-PDLC grating itself is a 2 ? 2 optical...
