ABSTRACT:
The present invention provides an independently addressable, vertical cavity surface emitting laser ("VCSEL") in the blue wavelength range of 390 to 430 nanometers. The gallium nitride-based laser structure is grown by selective area epitaxy and lateral mask overgrowth. By appropriate patterning of a dielectric mask on the gallium nitride layer on a sapphire substrate, areas in a second gallium nitride layer can have a low defect density upon which the remainder of the laser structure can be formed.
