Abstract
Semiconductor quantum wells (QW) have recently attracted much attention because of their electronic transport and optoelectronic properties[1]. The confinement of photocarriers in layers which thickness, Lz, is smaller than the bulk material Bohr radius, ao, reinforces the excitonic behavior, resulting novel nonlinear[2] and electro-optical properties[3]. In this talk we report recent investigations performed in our group on two topics; The extreme low and high intensity limit studies of AC-Stark Effect and the investigation of the dynamics of excitonic absorption in the infrared band gap InGaAs quantum wells. The first work was performed by W.H. Knox, J.B. Stark, D.S. Chemla, D.A.B. Miller, and S. Schmitt-Rink[4], and the second by M. Wegener, I. Bar Joseph, G. Sucha, M.N. Islam and D.S. Chemla[5].
