Absorber length optimisation for sub-picosecond pulse generation and ultra-low jitter performance in passively mode-locked 1.3 /spl mu/m quantum-dot laser diodes

摘要

Through absorber length optimisation, sub-picosecond pulse generation and ultra-low timing jitter are demonstrated in a 20 GHz passive mode-locked quantum-dot laser diode. Pulsewidths as low as 796 fs and timing jitter performance of 390 fs (20 kHz-50 MHz) are achieved.
