We report for the first time the generation of short optical pulses with oxide-isolated stripe, V-grooved AlGaAs-GaAs quantum wire diode lasers. The shortest pulse width of 21 ps is currently achieved for a 350 μm long uncoated device by a streak-camera, with electrical pulses of 350 ps wide and 15 V high. The spectral characteristics of the gain switched QWR laser are also presented.
