Mode Stabilization Mechanism of Buried-Waveguide Lasers with Lateral Diffused Junctions

The mode stabilization behavior of the buried active wave guide with lateral diffused junction is theoretically investigated. The study shows that for an active waveguide of width around 5 pm with a lateral diffused junction in the middle, the single fundamental transverse mode is preferred as the injection level is raised. The theoretical results are found to be in good agreement with experime...

Narrow ridge waveguide high power single mode 1.3-μm InAs/InGaAs ten-layer quantum dot lasers

Ten-layer InAs/In0.15Ga0.85As quantum dot (QD) laser structures have been grown using molecular beam epitaxy (MBE) on GaAs (001) substrate. Using the pulsed anodic oxidation technique, narrow (2 lm) ridge waveguide (RWG) InAs QD lasers have been fabricated. Under continuous wave operation, the InAs QD laser (2 · 2,000 lm) delivered total output power of up to 272.6 mW at 10 C at 1.3 lm. Under p...
