Abstract

We report experimental values for the nonlinear optical coefficients of AlGaAs, in the half-band-gap spectral region. The dispersion of the nonlinear refractive-index coefficient, n2, is measured for both TE- and TM-polarized light. We observe n2(TE) > n2(TM) and a ratio of cross-phase modulation to self-phase modulation (TE) of ∼0.95, as predicted from bandstructure calculations. The spectral dependence of the two- and three-photon absorption coefficients are also measured. Finally, the implications for all-optical switching and spatial soliton propagation are discussed.
