Abstract :
The device structure, fabrication process and properties of a new diffusion-type stripe-geometry injection laser are described. A V-groove etched into the laser surface determines the shape of the diffusion front and defines the stripe width. This V-groove laser operates stably in the fundamental transverse mode and exhibits linear kink-free light/current characteristics up to 25 mW per mirror.
