Abstract:
A process for use in fabrication of a semiconductor device,the fabricated semiconductor device comprising a top oxide aperture defined by a top oxidation layer, a bottom oxide aperture defined by a bottom oxidation layer, and a contact layer adapted for electrical contact and disposed between the top oxidation layer and the bottom oxidation layer, the fabricated semiconductor device presenting a central vertical axis, and the top oxide aperture and the bottom oxide aperture are collinear along the central vertical axis, wherein the semiconductor device includes a long-wavelength vertical cavity surface emitting laser (VCSEL) optically pumped by a short-wavelength VCSEL having a wavelength less than said long-wavelength VCSEL, the process comprising the steps of: etching past the top oxidation layer and stopping in the contact layer, etching one or more holes traversing the top oxidation layer and the bottom oxidation layer, and simultaneously oxidizing both the top oxidation layer and the bottom oxidation layer.
