To optimize the diffraction efficiency of Bi12SiO2 we studied the influence on that efficiency of three physical parameters (thickness of the sample, applied dc field, and light modulation depth m). We calculated the diffraction efficiency by using the refractive-index variation along the thickness of the sample and numerically solving the beam-coupling equations (for recording and reading). We found that for given values of m and the applied field there is an optimum thickness for which the diffraction efficiency is maximum. Diffraction efficiencies of 95% were obtained for high values of the light-modulation depth (m=1) and strong electric fields (20 kV/cm).
