摘要：
We have studied femtosecond pulse propagation in CdS quantum-dot-doped waveguides produced by the solgel and ion-exchange methods. The observed two-photon absorption and asymmetric spectral modulation of the transmitted pulses are explained by our theoretical model, which incorporates a near-resonant two-photon transition.
