Coupling kinetics of the photorefractive hologram

J Zhang, FTS Yu, DK McMillen - Applied optics, 1996 - opg.optica.org

found that the coupling between the adjacent channels increases as the reading time is …

Apodization effect of a reflection photorefractive hologram with linear absorption

Y Tomita, R Kuze - Optics communications, 2000 - Elsevier
New apodization mechanism of a thick reflection hologram recorded in a lossy
photorefractive medium is described and analyzed numerically. The result shows that linear …

Diffraction properties of a reflection photorefractive hologram

Noise analysis of photorefractive holograms under Gaussian beam illumination

QW Song, PP Banerjee, JJ Liu… - Journal of Modern …, 1992 - Taylor & Francis
Using a novel transfer function approach, we investigate the nature of the diffracted

Angle-dependent diffraction efficiency in a thick photorefractive hologram

H Zhou, F Zhao, FTS Yu - Applied Optics, 1995 - opg.optica.org
The diffraction from a thick photorefractive hologram is shown to be angular dependent,
which originates mainly from the angle-dependent effective electro-optic coefficient of a …
