We have produced a high efficient phase-only hologram, of which refractive index distribution is modified by using an ion exchange method. This paper describes an optimum condition of the phase profile of the hologram. In computer simulation, ion density and phase profile generated by ion exchanging is calculated. The diffractiion patterns of the gratings are calculated based on phase distribution data of the gratings. An optimum phase distribution is estimated. The optimum condition is verified experimentally.
