| Abstract: | Summary The existence of an optical nonlinearity of the Kerr-like type in a lyotropic liquid crystal is described in c.w. operation. The nonlinearity is found using the liquid crystal as a cladding material in a waveguide, or studying the interface properties between the liquid crystal and an ordinary glass. The used material is potassium caprillate and the nonlinearity is ascribed to thermal effects. Work performed with partial support from MPI-40% (Italian Education Ministry) and GNEQP-CNR (Italian National Research Council-Quantum Electronics Group). |
