Low-Threshold 795 nm Oxide-Confined Distributed Feedback Lasers With Surface Gratings

795 nm oxide-confined distributed feedback (DFB) lasers have been developed. The oxide-confined structure is used to realize lateral optical and current confinement, and the first-order surface gratings offer the frequency selectivity for single-longitudinal mode operation. The fabricated 200-&#...
