摘要: We perform characterization of the pulse shape and noise properties quantum dot passively mode-locked lasers (PMLLs). propose a novel method to determine RF linewidth timing jitter, applicable high repetition rate PMLLs, through dependence modal on mode number. Complex electric field measurements show asymmetric pulses with parabolic phase close threshold, appearance waveform instabilities at higher currents. demonstrate that can be overcome optical injection-locking continues wave (CW) master laser, leading time-bandwidth product (TBP) improvement, spectral narrowing, tunability. discuss benefits single- dual-tone sources injection additionally improve slave laser reduction below instrument limits (1 kHz) integrated jitter values 300 fs. Dual-tone allowed control over 25 MHz range all linewidths source linewidth, demonstrating phase-locking modes coherence improvement.
