Simulation of a ridge-type semiconductor laser with partially formed anti-guiding cladding layers
A ridge-type semiconductor laser with partially formed anti-guiding cladding layers is proposed, and lasing characteristics are simulated. With increases in the height and the width of the partially formed anti-guiding cladding layers, both kink-level and threshold current increase. When the height is 100nm and the width is greater than or equal to 15\(\upmu \hbox {m}\) for the partially formed anti-guiding cladding layers, kink-free operation is obtained up to the injected current of 2A. The lowest threshold current for the kink-free operation is 57.0mA when the height is 100nm and the width is 15\(\upmu \hbox {m}\) for the partially formed anti-guiding cladding layers.
