Abstract

The origin of optical nonlinearities of glasses doped with CdS_xSe_1-x microcrystallites is studied both experimentally and theoretically. At room temperature a large shift (≅50 meV) of the absorption spectrum to higher energies is observed in a CdS_xSe_1-x glass with increased light intensity. This blue shift is analyzed by using a semiconductor plasma theory. Experimental and theoretical results suggest that band filling is the dominant mechanism for the observed nonlinearity. An independent measurement for the intensity-dependent dispersive changes is presented.
