We investigate theoretically the main elements of manipulation of light pulses—strong
nonlinear slowing down, trapping, and release on demand—in photorefractive nonlinear …

We theoretically study the effect of light deceleration in photorefractive nonlinear media. This
includes consideration of different types of the photorefractive nonlinear response, different …

A slowing down of light pulses using backward-wave four-wave mixing is achieved in
photorefractive crystals with different coupling strength. The delay and width of the output …

Slowdown of Gaussian “dark pulses” in photorefractive crystal using a two-wave mixing
method is shown at room temperature. In agreement with our theoretical model, the …

We have theoretically investigated the main features of pulse deceleration and pulse-shape
transformations during phase conjugation in photorefractive nonlinear media. The main …

The beam fanning naturally occurring in a photorefractive crystal is shown to slow down a
single light pulse at room temperature. Slow light is demonstrated for both visible and …

It is shown experimentally and theoretically that photorefractive wave coupling can be used
for dramatic (≲ 0.025 cm/s) deceleration of light pulses whose width is larger than (or …

We investigate the possibilities of the backward four-wave coupling based on the nonlocal
photorefractive response for the nonlinear deceleration of light pulses. The presence of an …

The photorefractive effect [1] can loosely be defined as a light-induced change in the optical
properties of a material when the incident light is spatially nonuniform. The spatial …

The formation of patterns in two transverse dimensions in photorefractive two-wave mixing
with a single feedback mirror is investigated theoretically. We perform numerical simulations …
