Abstract
Self-pulsations in Phase Controlled Mode Beating lasers (PhaseCOMB) are very attractive for all-optical clock recovery at ultra-high bit rates. In this paper we apply the comprehensive simulation tool LDSL that has been developed by us for studying the self-pulsation features of PhaseCOMB lasers considering the effects of spontaneous emission noise, longitudinal spatial hole burning, and gain dispersion. In particular the importance of mode control for adjusting the PhaseCOMB operating conditions is pointed out. The simulation results are confirmed by measurements on fabricated devices. Index Terms-semiconductor laser, distributed feedback, modelling, self-pulsations, high speed, all optical signal processing, R-regeneration.
