Abstract:
A monolithic array of vertical cavity surface emitting laser devices that emits light at more than one wavelength comprising:a III-V semiconductor substrate; a plurality of vertical cavity surface emitting lasers formed on the III-V substrate, wherein a first portion of the plurality of vertical cavity surface emitting lasers emit light at a first wavelength and a second portion of the plurality of vertical cavity surface emitting lasers emit light at a second wavelength, wherein each device has a top mirror, a bottom mirror, a cavity region comprising a top separate confinement layer, a bottom separate confinement layer, and an active region, wherein the active region further comprises at least one quantum well layer bounded on each side by a boundary layer and wherein the at least one quantum well layer is about equidistant between the top separate confinement layer and the bottom separate confinement layer and the thickness of the at least one quantum well layer of the vertical cavity surface emitting lasers that emit light at the first wavelength is different than the thickness of the at least one quantum well layer of the vertical cavity surface emitting lasers that emit light at the second wavelength.
