Abstract

Stabilization of thermodynamic relaxation of photoinduced cis isomers of azobenzene liquid-crystal molecules is observed in nanoparticulate networks. The phenomenon permits bistability of the phase state (anisotropic and isotropic) of the material and reversible all-optical switching between those states, resulting in strong changes in the light-scattering properties of the material. Recording of complex optical structures with high spatial resolution with the aid of laser beams of different wavelengths is demonstrated.

Recording a linear region of a nematic phase with a red λ=633 nm laser beam in the area of the network-stabilized isotropic phase of the LC. (a) The time constant of isotropic–nematic relaxation as a function of the laser beam power. Inset, area of thermodynamically stable isotropic phase (dark area) generated by a violet laser beam observed under a polarizing microscope with crossed polarizers. The scattering linear region in the dark area corresponds to the nematic phase obtained by scanning of the material across a focused He–Ne laser beam. (b) Reversible optical switching of the transmission state of the material. The intensity of the violet radiation is periodically modulated (shaded area), whereas the intensity of the He–Ne laser beam is kept constant.
