First demonstration of the gain switching characteristics of an AlGaAs-GaAs V-grooved quantum wire laser

摘要

We report for first time generation of short optical pulses with oxide-isolated stripe, V-grooved AIGaAs-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.
