Abstract We demonstrate the "reversed-mode" polymer-stabilized liquid crystal device. The incidence light goes through the film without the applied voltage and is diffracted with it. Because of relatively high liquid crystal percentage of 94%, the operating voltage of the device is less than 20V. We explain this phenomenon using the molecular orientation model and the refractive index profile. The device can be used as display, optical switch, optical modulator and especially optical cross-connect deflector.
