A new principal mechanism underlying real-time holographic grating recording in a thin cell filled with a nematic liquid crystal doped with a dye is proposed. In the experiment a laser light interference pattern is mapped in the form of a spatial modulation of index of refraction. This is achieved b
process offers a simple, non-lithographic way to fabricate twodimensional periodic nanostructures. Such regular alumina nanopillar arrays with an adjustable lattice constant (90Β± 300 nm) are suitable for two-dimensional photonic bandgap structure materials for use in UV-vis wavelength regions.

We report in this work on the simultaneous presence of both positive and negative nonlinear optical (NLO) refractive indexes measured in methyl-red dye doped 5CB liquid crystal (LC). Characterization of these materials was performed according to the Z-Scan technique under cw He-Ne laser irradiation,
