Abstract

The optical properties of T-shaped GaAs/AlGaAs quantum wire (QWR) waveguide structures are studied with a magnetic field oriented parallel or perpendicular to the QWR axis. The QWRs were fabricated by the cleaved edge overgrowth (CEO) technique. At low values of the magnetic field oriented perpendicular to the QWR axis, a strong increase in the light emission intensity is observed for all ...
