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

Light-induced charge transport processes are essential for photorefractive effects in
electrooptic crystals. Charge driving forces, charge transport models and experimental …

Reflecting changes in the field in the ten years since the publication of the first edition, The
Handbook of Photonics, Second Edition explores recent advances that have affected this …

We have grown and optically characterized strontium‐barium niobate crystals, including
both undoped and cerium‐doped crystals having two different Sr/Ba ratios (61/39 and …

The photorefractive effect is now firmly established as one of the highest-sensitivity
nonlinear optical effects, making it an attractive choice for use in many optical holographic …

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 present experimental data for BaTiO_3 that exhibit an intensity dependence in the
absorption coefficient and the two-beam coupling coefficient at intensities between 0.002 …

The characteristics of an interferometric system based on two-wave mixing at 1.06 μm in
photorefractive InP: Fe under an applied field for the detection of ultrasonic motion of a …

For a large photorefractive efficiency, suitable donors or traps and efficient charge migration
are necessary [2.1]. In undoped crystals the traps are provided by small traces of impurities …

We analytically solve charge-transport equations for a photorefractive crystal with shallow
and deep traps. We predict that, if shallow traps can accumulate a high density of charge …
