Two-photon absorption spectroscopy in GaAs quantum wells

Not Accessible

Abstract

Because the two-photon transition selection rules are different from those for linear absorption, levels which are not accessible In one-photon spectroscopies can be observed. Here we report an experimental investigation of two-photon absorption (TPA) spectroscopy in GaAs/AIGaAS quantum well structures. Experiments employed a waveguide geometry to enable the polarization of the incident light ε̂ either perpendicular or parallel to the confinement direction ẑ. Two samples with well thickness lz of 40 and 110 Å were used. Distinct differences in TPA between the two polarization Configurations were observed and shown in Figs. 1 and 2.
