TLDR
In this paper, a self-pumped phase conjugation in a photorefractive liquid crystal light valve with a tilted feedback mirror is reported, which can in general be applied to thin nonlinear layers, opening the way to distortion correction applications of thin media.Abstract:
We report self-pumped phase conjugation in a photorefractive liquid crystal light valve with a tilted feedback mirror. This is a new scheme for the self-generation of a phase-conjugate replica and can in general be applied to thin nonlinear layers, opening the way to distortion-correction applications of thin media.read more

Beam coupling in photorefractive liquid crystal light valves
TL;DR: In this article, the beam coupling in photorefractive liquid crystal light valves (LCLVs) was studied. And the authors showed that the two-beam coupling gain can be enhanced by the Talbot effect related to multi-passage of the beams through the successive layers of the nematic liquid crystal.

Amplified reflection, phase conjugation, and oscillation in degenerate four-wave mixing
Amnon Yariv,David M. Pepper +1 more
TL;DR: A number of new optical effects that result from degenerate four-wave mixing in transparent optical media are proposed and analyzed and are relevant to time-reversed (phase-conjugated) propagation as well as to a new mode of parametric oscillation.

Hexagonal spatial patterns for a Kerr slice with a feedback mirror.
TL;DR: Analytically and numerically a very simple nonlinear optical system, a thin slice of Kerr material with a single feedback mirror, shows that for both a focusing and defocusing medium the plan-wave solution is unstable above a certain input intensity, and a hexagonal pattern of bright spots should form.

Spontaneous Oscillation and Self-Pumped Phase Conjugation in a Photorefractive Polymer Optical Amplifier
TL;DR: In this paper, a two-layer sample placed in an optical cavity made with two concave mirrors, spontaneous oscillation due to two-beam coupling gain was observed for an applied electric field of 75 volts per micrometer, marking a milestone for this growing class of optoelectronic materials.
