Using a new model based on the so-called perturbational approach, we present a theoretical analysis of nonlinear multiple-grating interaction in diffusion-dominated …
R Saxena, C Gu, P Yeh - JOSA B, 1991 - opg.optica.org
We examine simultaneous write–read of dynamic photorefractive gratings for arbitrary phase shifts between index grating and intensity pattern. The nonlinear behavior of diffraction …

We present a comprehensive analysis of the evolution of a grating envelope, in both transmission and reflection geometry, during the erasure process in various readout …
F Vachss, L Hesselink - JOSA A, 1988 - opg.optica.org
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 …
C Gu, J Hong, P Yeh - JOSA B, 1992 - opg.optica.org
We consider the diffraction properties of index gratings in photorefractive media, assuming an arbitrary momentum mismatch (Bragg mismatch). The incident and diffracted waves …
Y Tomita, S Matsushima - JOSA B, 1997 - opg.optica.org
We investigate the role of temperature-dependent ionic and re-created photocarrier (hole) gratings in self-enhanced readout from thermally fixed holographic gratings in undoped …
For most regimes descriptions of photorefractive behavior by electron–hole transport with a single species of impurity levels and by electron–hole transport with two species of impurity …
MC Bashaw, JF Heanue - JOSA B, 1997 - opg.optica.org
We investigate photorefractive media for which quasi-stabilized ionic gratings can be used to prolong readout lifetime. We use coupled-transport-mode theory to describe the …
