Abstract

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.
