Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

We analyze self-trapping of one-dimensional optical beams in photorefractive, photovoltaic
media for open-and closed-circuit realizations. We show that a passive load (resistor) in the …

Photorefractive Materials presents an overview of the basic features and properties of
photorefractive materials, covering a wide array of related topics. It provides a coherent …

We develop a theory of high-temperature photorefractive phenomena in LiNbO 3 crystals
related to the problem of thermal fixing and storage of optical information. The theory covers …

We report a theoretical model for a photorefractive running hologram in bulk-absorbing
materials in the presence of self-diffraction and use this model to analyze experiments for …

We report the measurement of the diffusion length, the Debye screening length and the
quantum efficiency of photoelectron generation in strongly light absorbing photorefractive Bi …

We report a direct observation of space charge waves in photorefractive crystals with point
group 23 (sillenites) based on their penetration into an area with uniform light illumination. It …

We report an analysis of the feedback circuit operation that produces fringe-locked
photorefractive running holograms. In agreement with theoretical expectations we …

Theoretical and experimental investigations of the linear and nonlinear space–charge field
effects in photorefractive materials are reviewed. In particular, the aim is to explore the …

The grating translation technique (GTT), which employs a momentary shift of light fringes
during holographic recording, is a powerful tool for characterization of nonlinear materials …
