5 January 2004 Supra-photorefractivity in C60- and carbon-nanotubes-doped nematic liquid crystals
Author Affiliations +
We report theoretical and experimental studies of supra-photorefractive nematic liquid crystals doped with C60 and/or Carbon nanotubes. Theoretical estimate shows that the nonlinear refractive index change coefficient n2 in such systems can be >> 1 cm2/Watt. Experimentally, we have observed n2 of ~ 10 cm2/W, with typical nematic response times.
