    Abstract

    The two-photon absorption coefficient and induced nonlinear refractive-index in both TE and TM modes of GaAs/AlGaAs multiple quantum well strip-loaded channel waveguides are measured in the wavelength range from 1490 nm to 1660 nm. The two-photon absorption coefficient ranges from almost zero to 12 cm/GW and the nonlinear refractive-index is always in the order of 10(-13) cm(2)/W in the wavelength window investigated. Strong nonlinear anisotropy is observed. The values of the two-photon absorption coefficient are obtained by calibrating the inverse transmission measurements. Those of the nonlinear refractive-index are obtained by monitoring the signal spectrum broadening due to self-phase modulation. The wavelength dependences of the measured two-photon absorption coefficient and nonlinear refractive-index are reasonably consistent with the theoretical predictions.
