A numerical approach has been developed for simulating the recording and erasure kinetics
in photorefractive materials for high modulation of the light-intensity pattern. The recording …

In this chapter, the standard model accounting for the photorefractive nonlinearity in a
material is presented. The mathematical formalism of the rate equations has been …

The photorefractive grating formation dynamics were modeled numerically for bismuth
silicon oxide under conditions of stationary recording with a dc applied electric field. These …

The use of photorefractive materials such as Bi 12 SiO 20 as dynamic holographic media is
becoming an interesting alternative to that of the current liquid-crystal-based modulators in …

The observation of diffraction spots from strong higher-order combinational gratings during
sequential recording of two photorefractive holograms in a LiNbO_3 crystal is reported. To …

Phase mismatches with regard to light of photorefractive gratings have been investigated for
arbitrary modulation depths of the illuminating pattern. The time evolution of the phases …

The transient behavior of the fundamental amplitude of the photorefractive space-charge
field is derived without restrictions within the band transport model. The two-wave mixing …

Optical bias has been applied in the formation of moving gratings in bismuth silicon oxide at
large fringe modulations. It is shown that optical bias is an effective method of overcoming …

Bismuth metal oxide sillenites ($ Bi\sb {12} SiO\sb {20} $, $ Bi\sb {12} GeO\sb {20} $, and $
Bi\sb {12} TiO\sb {20} $) are widely used as photorefractive elements in optical systems …

The defects which are responsible for the photorefractive effect in the sillenites are most
likely point defects. However, the various grating experiments do not directly identify these …
