| Abstract: | This letter describes a novel planar stripe-geometry injection laser (termed the Swan laser), showing a single transverse and longitudinal mode operation, made by a simple fabrication method. This stripe geometry is composed of a main stripe section with a width of ?10 ?m and a mode-control section with a nominal width near the carrier diffusion length less than 5 ?m; the shape looks like a waist/notch along the stripe. The kink of the light output does not appear at a power level of more than 20 mW/facet. |
