We present a review of the main results reported during about two decades on light-induced phenomena in liquid crystal samples doped by the azo-dye Methyl-Red. The aim is to give a unifying picture of the different observed effects which have been demonstrated to be originated form the competition of light-induced adsorption and desorption phenomena at the illuminated boundary surface. They give rise either to colossal nonlinearity or to light-induced anchoring and memory effects and have a potential interest for photonics applications.

甲基红掺杂液晶中光诱导的吸附和解吸：综述

我们介绍了大约二十年来报道的有关偶氮染料甲基红掺杂的液晶样品中光致现象的主要结果。目的是给出不同观察到的效果的统一图片，这些效果已被证明是由于受照边界表面上光诱导的吸附和解吸现象的竞争所致。它们引起巨大的非线性或光诱导的锚定和记忆效应，并且对光子学应用具有潜在的兴趣。
