Paper Abstract

High diffraction efficiency of each grating is desired to reduce light intensity loss when gratings are integrated to realize miniaturization for 3-D optical instruments in LiNbO3 crystals. Based on jointly solving the two-center material equations, oscillating behavior of diffraction efficiency during recording and erasing process is investigated theoretically to realize maximized diffraction efficiency for integrated volume grating instruments in weak oxidized doubly-doped LiNbO3:Fe:Mn crystals. Two nonvolatile gratings are integrated and nonvolatile diffraction efficiency for each grating exceeds 60%. These methods depend on the dopant elements and its concentrations, annealing (or oxidation-reduction) in doubly-doped LiNbO3 crystals, and recording and sensitizing intensities and wavelengths. The experimental investigation will be performed to verify the calculated results.
