✦ Synopsis

Lasing from the ground state electron and heavy-hole-like transition of quantum wire (QWR) is demonstrated for the ÿrst time at room temperature, with an oxide-isolated V-grooved GaAs=AlGaAs triple QWR laser grown by ow-rate modulation epitaxy (FME). The lasing peaks at all temperatures (4 -300 K) are in reasonably good agreement with both the photon energies of the peaks of the photoluminescence curves and the numerical calculation of the electronic sub-band energy states of the corresponding QWR structure. These results are considered to be responsible for the reduced heterointerface inhomogeneities (the Stokes shift ∼0:3 meV) of the FME grown QWR, giving a low-loss wave guide in the QWR laser.
