Abstract :
In this paper, we report the results of a series of experiments conducted in liquid crystal cored fibers, where we have observed several nonlinear optical phenomena with relatively much lower optical threshold fluence. In particular, passive all-optical limiting action has been found to occur at threshold fluence a few times smaller than their thin film or bulk cell counterpart. Concomitant to these observations, stimulated back scattering and nonlinear pulse propagation effects also appear
