Abstract :
A novel mid infrared emitting GaAs/AlGaAs quantum wire cascade device is presented that is fabricated using the cleaved edge overgrowth technique. The samples are pumped electrically. Radiative electronic transitions between discrete energy levels in coupled quantum wires are calculated for such a structure. Operation current dependent mid infrared emission is observed at a peak wave number of View the MathML source with a full-width at half-maximum of View the MathML source at a heat sink temperature of View the MathML source. The presented sample is an experimental proposal for an unipolar quantum wire intersubband laser.
