We report a theoretical investigation of the frequency response of optical interference filters
written in photorefractive materials. Counterpropagating coherent beams interact in the …

We have analytically solved the problem of N mutually incoherent pairs of beams in
photorefractive media, each pair of which shares a common grating. The results are applied …

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

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 examine simultaneous write–read of dynamic photorefractive gratings for arbitrary phase
shifts between index grating and intensity pattern. The nonlinear behavior of diffraction …

The diffraction properties of fixed volume gratings, including the effect of additional
photorefractive energy coupling between the incident wave and the diffracted wave, are …

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 …

A coupled-wave analysis is given for a mixed hologram grating. The effect of spatial
dephasing between the absorption and phase grating which was previously presented in …

A mechanism for recording a static hologram in a photorefractive crystal in an externally
applied ac field is investigated. One beam is rapidly modulated, and the interference pattern …

The intensity and phase of two counterpropagating optical beams in a photorefractive
material are investigated both numerically and by using an approximate analytical theory. It …
