Abstract

Passive harmonic mode-locked laser diodes are capable of generating pulses at repetition rates in excess of 1.5 THz. Harmonic mode-locking techniques fall into two main categories: colliding pulse mode-locking (CPM) and compound cavity mode-locking (CCM). We report simulations and experimental results using a hybrid approach which combines the CPM and CCM techniques in a multi-section laser diode with an external reflector. The experiments were performed with a 650 μm-long 3-section GaAs/AlGaAs quantum well ridge waveguide laser diode with a 30 μm-long saturable absorber section located in the middle of the cavity
