Picosecond pump–probe interferometric measurement of optical nonlinearities in channel waveguides

Abstract

An interferometric technique for measuring with picosecond resolution the time evolution of the real and imaginary components of optical nonlinearities in channel waveguides is described. Characteristics of the technique are illustrated with measurements of band-filling optical nonlinearities in CdS_xSe_1−x-doped glass channel waveguides.
