Abstract
A simple robust self-seeded laser diode scheme for generating electrical wavelength-tunable picosecond pulses at a fixed repetition rate is presented. Wavelength tuning of transform-limited pulses with a pulsewidth of ~ 10 ps and a sidemode suppression ratio of 15 dB overall, and 28 dB at best, was obtained among six cavity modes corresponding to a tuning range of 7.6 nm. Very stable operation was observed at each wavelength because there was a relatively large locking range for each wavelength.Keywords
