In recent years a considerable effort has been aimed at developing and characterizing glasses with large and fast optical nonlinearities, motivated largely by the potential application of these materials in all-optical switching devices. We will review our work in this area, with a focus on femtosecond measurements of new materials at 1.3 and 1.55 microns. These provide all possible information about the nonlinear response of the materials. Recent studies of As-S-Se, Ge-As-Se, and Ge-As-S-Se glasses reveal several materials with nonlinear refractive indices 1000 times larger than that of fused silica, as well as materials with figures of merit that are adequate for effective optical switching. These studies also provide information about the dispersion of the nonlinearities, which in turn sheds light on the mechanisms responsible for the nonlinear response.
