Abstract

We investigate the effects of the recording-erasure dynamics on the storage capacity of a wavelength-multiplexed reflection-type photorefractive hologram by using a coupled-recording-wave approach. A closed-form expression for the diffraction efficiency for on-Bragg incidence is derived. The dependence of the equalized diffraction efficiency on the number of recordable holograms is analyzed. The result shows that the storage capacity of a reflection-type hologram is of the same order of a transmission-type hologram but higher than the previous predictions based on an uncoupled-recording-wave theory.
