Abstract
We report the result of a detailed spectroscopic investigation of the optical properties of excitons in rectangular (etched) and V-shaped (grown on non-planar substrates) GaAs quantum wires. High index excitonic transitions and strong polarization anisotropy of the optical spectra have been observed. The experimentally observed trasitions are in agreement with the theoretical evaluation of quantized energy levels based on the respective model potential.
