ABSTRACT:
A monolithic laser structure has an infrared laser structure stacked on top of a red laser structure. An ion implantation channel from the substrate of the infrared laser structure to the lower cladding layer of the red laser structure lets both laser structures use a common electrode on the substrate of the red laser structure. A portion of the monolithic structure is etched down to the red laser structure for the electrode of the red laser structure. The monolithic laser structure has a red and infrared side by side array from the two stacked red and infrared laser structures. The red and infrared laser structures can each have native oxide confined ridge waveguides.
