Nondegenerate two-photon absorption in GaAs/AlGaAs multiple quantum well waveguides
We present femtosecond pump-probe measurements of the nondegenerate (1960-nm excitation and 1176–1326-nm probe) two-photon absorption spectra of 8-nm GaAs/12nmAl_{0.32}Ga_{0.68}As quantum well waveguides. Experiments were performed with light pulses copolarized normal and tangential to the quantum w...
