We report the experimental evidence of a nonlinear optical response among the highest
ever observed. A nonlinear refractive index on the order of 103 cm2/W (that is 108 times …

Soliton induced waveguides can be all-optically readdressed in planar cells by modifying
the molecular anchoring with an external light source. Using an elliptically shaped control …

Precious metals and liquid crystals (LC) are quite different yet share some common features,
for example, their beauty, distinguished optical properties and a competition of high prices …

The work focuses on recent developments of the rapidly evolving field of Non-conventional
Liquid Crystals. After a concise introduction it discusses the most promising research such …

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 …

We report on the effects of a low-frequency electric field on the optical nonlinear response of
thin dye-doped liquid crystal cells. Experimental data show that the external field allows …

We show that both the extraordinarily large nonlinear response and the light-induced
permanent reorientation in liquid crystals doped by the azo dye methyl red originates from …

We report a critical enhancement of the nonlinear optical response of dye-doped liquid
crystals obtained by approaching the clearing point in the nematic phase. The enhancement …

A detailed study of the light-induced gratings in Methyl-Red-doped 4-n-pentyl-4′-
cyanobiphenyl (5CB) homeotropically aligned is reported. In particular, the dependence of …

We have carried out a detailed experimental study, by means of x-ray reflectometry (XRR)
and half-leaky guided mode (HLGM) optical characterization, of the light-induced molecular …
