Abstract
Photorefractive materials can be used in a wide range of applications in optical signal processing such as optical interconnections, novelty filters, real-time holography, etc. Since the first observation of the spatial subharmonics by Mallick et al.1 in photorefractive Bi12SiO20 crystal in 1988, there have been further intensive works on this new phenomena in both theory and experiments.2 However, most of the work in this field has been concentrated on obtaining the instability condition for the generation of subharmonics. We start with a nonlinear partial differential equation for the varying part of the space charge field Esc in a moving co-ordinate (ξ = Kx − Ωt) system.2
