High power 1.5-μm InGaAsP/InP Colliding-Pulse Mode-Locked Slab-Coupled Optical Waveguide Laser

We have demonstrated the first SCOWL operating in a colliding pulse mode-locked configuration. This laser has a repetition rate of 8.54 GHz with ≫70 dB fundamental mode suppression and average output power of 170 mW per facet. We measured a detection limited pulse width of 20 ps. The resultant pulse energy and peak power are 19.9 pJ and 1 W, respectively.
