Monolithic passively mode-locked semiconductor quantum-well laser emitting at 1070 nm: Picosecond pulse generation and pulse train stability analysis

We study experimentally the pulsed emission of a passively mode-locked multi-section quantum-well semiconductor laser emitting picosecond short optical pulses at a fundamental repetition rate of 20 GHz and at a wavelength of 1070 nm. We identify different regions of picosecond short pulses dependent on the laser biasing conditions and relate them to the investigated mode-locking stability by means of timing jitter and amplitude jitter analysis. We obtain timing jitter values in a two-digit femtosecond range and operating regions without relative amplitude jitter at pulse widths in the order of a few picoseconds.
