Abstract
None:
We present 50 GHz colliding pulse buried heterostructure InAs/InP quantum dot mode-locked lasers with asymmetric facet coatings. Compared to conventional two-section BH InAs/InP quantum dot mode-locked lasers, these devices demonstrate substantially narrower RF linewidths, lower RIN, and narrower optical linewidth.
