Abstract-Mode Locking at THz Repetition Frequencies using Lasers with Phase Shifted Sampled Gratings
Mode-locking at repetition frequencies of 800 GHz and 1 THz is reported in pi-phase-shifted sampled grating distributed-Bragg-reflector (DBR) lasers. The effective coupling coefficient of the phase-shifted gratings is twice that of conventional sampled grating DBRs.
