Abstract

In this paper, a very effective recording technique of optimal recording/fixing switching time induced by high-coupling effect is considered for high diffraction efficiency of local nonvolatile holographic gratings in LiNbO₃:Ce:Cu crystals. The fixed diffraction efficiencies gained by optimal switching time are up to 100% in theoretical simulations and 78% in experiments. It provides a new idea to obtain high persistent diffraction efficiency. Finally, as one of examples for design of 3-D optical integrations by local nonvolatile holographic gratings, a new type of volume holographic grating lenses for converting a plane wave to a lateral-spread spherical wave and vice versa, is illustrated.
