Liquid crystals can be used in devices made for lasing and switching purposes and photonic crystal structures by mixing with polymers .One of the applications of LC is in fabrication of switchable gratings. These gratings are based on holographic recording of coherent light in the mixture of polymer and LC. This process is called holographic polymer dispersed liquid crystal (HPDLC). The goal of this article is fabrication and characterization of two dimensional HPDLC grating. After fabrication, electrooptical switching has been tested. A special prism is used in optical recording setup. Electrooptical tests has been done in both A.C and D.C switching methods.
