Abstract
Liquid crystals in their various phases have been shown to possess large optical non-linearities over a wide temperature and spectral range.1,2 Consequently, almost all types of nonlinear optical phenomena have been observed in bulk thin film or liquid cells.2 In this paper, we report the results of a series of experiments conducted in liquid crystal cored fibers and slab waveguides (c.f., Fig. 1), where we have observed several nonlinear optical phenomena with relatively much lower optical threshold fluence.
