Abstract

V-grooved inner stripe (VIS) GaAs-AlGaAs quantum-wire (QWR) lasers were successfully fabricated by combining two-step metalorganic chemical vapor deposition (MOCVD) growth with a wet-etching technique. In order to achieve low threshold current density and high reliability, a conductive stripe width (W), a thickness (t_p-CBL), and a doping concentration (n_p-CBL) of the p-GaAs current-blocking layer (CBL) were determined to be W = 1.2 μm, t_p-CBL = 2 μm, and n_p-CBL = 1 × 10¹⁸ cm^-3. The leakage currents passing through the CBL were also estimated using a modified P-SPICE. Thus far, a threshold current of 45 mA and an output power of 4 mW at 51 mA have been achieved under room-temperature pulsed operation for some devices with uncoated facets.
