Abstract

We report a 10-GHz ring resonator colliding pulse mode-locked (CPM) laser with tunable couplers for InP-based monolithically integrated optical coherent communication system applications. Optimization included adjusting the saturable absorber reverse bias, driving RF-frequency, and amplifier gain current. Hybrid mode-locking (HML) resulted in a minimal pulse width of 10.1ps for 6 nm spectral width.
