Paper Abstract

In this paper, we have developed a novel optical switch based on the electronically switchable Bragg gratings (ESGB) in holographical polymer dispersed liquid crystals (H-PDLC), which is adopted in the U.S. Patent (NO.09/963, 939). This optical switching can be produced by the superposition of H-PDLC Bragg gratings with different spatial frequencies and very high diffraction efficiency. It can provide switching speeds faster than 5ms, so that the technique can be widely applied in telecommunication to improve the transmission speed effectively.
