A one-dimensional active region consisting of 20-period T-shaped GaAs/AlGaAs quantum wires of $14\times 6$ nm2 combined with a well-defined current-confinement scheme has been utilized to obtain a low-threshold-current high-efficiency laser. A threshold current as low as 0.27 mA, a single-mode cw output power of 0.13 mW at 1 mA injection current, and a differential quantum efficiency of 12% were achieved at 30 K using a quantum-wire laser with a 500-μm-long Fabry–Perot cavity coated by high-reflectivity thin metals.
