Paper Abstract

Two-dimensional (2-D) square lattice (SL) photonic crystals (PCs) are fabricated and their optical/electro-optical properties are studied. The PCs are based on polymer-dispersed liquid crystals (PDLC) that are formed using twobeam interference with double-exposures. The PC structure that is observed using a scanning electron microscope (SEM) matches with the calculated interference pattern. The results of optical/electro-optical studies demonstrate that superprism and negative refraction effects occur at certain incident angles over a range of frequencies, and are consistent with the simulated ones. Moreover, the negative refraction efficiency is electrically controllable.
