Abstract

Demonstration of supraoptical nonlinearity in liquid crystals was discussed. Studies showed that the extremely strong light scattering properties of nematic liquid crystals (NLC), could be used for self-action effects with unprecedented low optical power in very thin film. Supranonlinearities were recently discovered in methyl red dye molecules, C60 and carbon nanotube doped NLC. These supraoptical nonlinearities have enabled many nonlinear processes, like optical limiting and image processing, with even lower operating power thresholds.
