J. S. Weiner, D. B. Pearson, D. A. B. Miller, D. S. Chemla, D. Sivco and A. Y. Cho, "Nonlinear Spectroscopy of InGaAs/InAlAs Multiple Quantum Well Structures," Appl. Phys. Lett. 49, 531-533 (1986).

The first investigation of nonlinear absorption in InGaAs/InAlAs multiple quantum wells using picosecond and CW infrared lasers is presented. The nonlinearity is demonstrated to be due to plasma-induced excitonic bleaching. The measured saturation densities agree with those predicted by theory
