Terahertz-bandwidth coherence measurements of a quantum dash laser in passive and active mode-locking operation
Résumé
This research carries out coherence measurements of a 42.7GHz quantum dash (QDash) semiconductor laser when passively, electrically and optically mode-locked. Coherence of the spectral lines from the mode-locked laser is determined by examining the radio frequency (RF) beat-tone linewidth as the mode spacing is increased up to 1.1THz. Electric field measurement of the QDash laser are also presented, from which a comparison between experimental results and accepted theory for coherence in passively mode-locked lasers has been performed.
