Holographic gratings recorded by photopolymerization of liquid crystalline monomers have been immediately and reversibly developed, or switched, by application of electric fields. Diffraction efficiency modulation has exceeded 200-fold, with maximum efficiency about 13% in the on state for 10 im samples. Fixing of the holograms in the more efficient state has been accomplished by short exposure to a single writing beam. Microscopic images of the switching gratings recorded on videotape have provided information about grating structure and supported our proposed mechanism for the recording and switching effects.
