Patent ID: 8111729

Claim:
A wafer platform device for a multi-wavelength array of hybrid silicon lasers, the lasers in the array capable of emitting light at different wavelengths simultaneously, the device comprising: a silicon-on-insulator wafer including patterned parallel waveguides; and a III-V wafer bonded to the silicon-on-insulator wafer, and comprising multiple layers having a plurality of different gain sections within the III-V wafer, wherein the different gain sections are formed using quantum well intermixing, and wherein the different gain sections are oriented perpendicularly to the patterned parallel waveguides, wherein the multiple layers of the III-V wafer comprise an n-type InGaAsP/InP superlattice layer and an n-type InP layer, wherein the n-type InP layer is disposed between the n-type InGaAsP/InP superlattice layer and the silicon-on-insulator wafer.
