Nondegenerate Two-Photon Absorption in GaAs/AlGaAs Multiple Quantum Well Waveguides

Nicholas Cox, Junxiong Wei, Himansu Pattanaik +4

We present femtosecond pump-probe measurements of the nondegenerate (1960nm excitation and 1176--1326nm probe) two-photon absorption spectra of 8 nm GaAs/12nm Al$_{…
