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 higher than in Giant Optical Nonlinearity) has been obtained in randomly oriented thin liquid crystal cells. This result shows the fundamental role played by the surface in the nonlinear optical response of dye-doped liquid crystals.

Abstract
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 higher than in Giant Optical Nonlinearity) has been obtained in randomly oriented thin liquid crystal cells. This result shows the fundamental role played by the surface in the nonlinear optical response of dye-doped liquid crystals.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
