Dynamic Grating

The principal optical nonlinearities of isotropic liquid crystals are reviewed, and their potentials for all-optical limiting and switching applications are assessed. Our dynamic grating studies of a class of isotropic liquid crystals show that, in the nanosecond and longer time scales, the principal mechanisms for nonlinearities are laser induced ordering (molecular orientations), thermal and density fluctuations. We report optical limiting results obtained with bulk thin film and optical fiber fabricated from these isotropic crystals.
