Abstract :
High repetition rate picosecond pulses with low uncorrelated timing jitter (down to ~0.25 ps) have been generated at 1.55 μm from gain- and Q-switched InGaAsP lasers without external feedback. Experiments were carried out at multi-gigahertz frequencies on one- and two-section devices; timing jitter was estimated from spectral measurements. Sub-picosecond values were found above ~5 GHz for optimally-biased one-section DFB lasers in gain-switching. Values more than two times lower were obtained from Q-switched quantum well two-section lasers, with RF modulation applied to a fast absorber section
