Abstract:
A vertical-cavity surface-emitting laser (VCSEL) includes a first reflector having a first reflectivity; a second reflector having a second reflectivity, where the second reflectivity is less than the first reflectivity; a gain region between the first and second reflectors; and a substrate having a first surface and a second surface, where the first surface is coupled to the second reflector, and where the second surface is formed into a lens to act upon light emitted by the VCSEL through the substrate. The VCSEL lases in a single transverse mode.

Claim (Index 10):
In a method for fabricating a single transverse mode VCSEL comprising:\n depositing a ring-shaped electrically conductive material on a first reflector, wherein the first reflector is coupled to a light generation region, the light generation region is further coupled to a second reflector, and the second reflector is coupled to a first surface of a substrate; depositing a hard mask layer over the ring-shaped electrically conductive material; removing material from the first reflector and the light generation region to form a wide mesa beneath the hard mask layer; oxidizing a portion of a layer in the first reflector containing aluminum to create an oxide aperture; and depositing an ohmic contact layer on the second reflector surrounding the wide mesa, wherein an improvement comprises:\n removing the hard mask layer; \n depositing an oxide layer on the wide mesa; \n removing portions of the oxide layer to leave a remaining oxide layer within the ring-shaped electrically conductive material, wherein at least a portion of the remaining oxide layer has a thickness that is approximately a quarter of a wavelength, and further wherein the VCSEL lases in a single transverse mode at the wavelength; and \n depositing a metallic reflector layer on top of the quarter wavelength thickness of the remaining oxide layer, wherein the metallic reflector layer is anchored to the ring-shaped electrically conductive material.
