Abstract

We present a T-shaped waveguide for a quantum-wire intersubband laser in the GaAs/AlGaAs heterosystem for the midinfrared spectral region around 8 mm. Such a device is fabricated using the Cleaved Edge Overgrowth (CEO) technique. The suggested waveguide structure is compatible to this growth technique. The confinement factor and the waveguide losses due to free carrier absorption are ...
