Abstract
Mid-infrared (lambda = 3.25 mu m) broadened-waveguide diode lasers with act ive regions consisting of 5 type-II "W" quantum wells operated in continuou s-wave (cw) mode up to 195 K. At 78 K, the threshold current density was 63 A/cm(2), and up to 140 mW of cw output power was generated. A second struc ture with ten quantum wells operated up to 310 K in pulsed mode.
