We consider the diffraction properties of index gratings in photorefractive media, assuming
an arbitrary momentum mismatch (Bragg mismatch). The incident and diffracted waves …

Recording angularly multiplexed holograms in photorefractive media requires an
understanding of both the recording and erasure dynamics. In this paper a coupled‐wave …

The response of photorefractive materials to sinusoidal intensity patterns of high modulation
depths is considered. It is shown that the induced refractive-index response in this regime is …

A general analytical model is developed for analysis of the diffraction properties of layered
structures of photorefractive gratings. With this model a simple closed-form expression is …

We consider the possibility of restoration and/or enhancement of decaying holograms in
photorefractive media by using a simple optical readout in conjunction with a phase …

We demonstrate the nonlinear recovery of diffused images in a self-focusing photorefractive
medium. The method is based on the convolution property of nonlinearity, in which related …

The erasure kinetics of holographic gratings has been theoretically studied for a material
containing two photorefractive species. The approach is an extension of the method …

We provide a detailed analysis of gray spatial optical solitons in biased photorefractive
media. The properties associated with these solitons, such as their transverse velocity …

We propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …
