Abstract:
VCSELs and methods having improved characteristics. In some embodiments, these include a semiconductor substrate; a vertical-cavity surface-emitting laser (VCSEL) on the substrate; a first electrical contact formed on the VCSEL; a second electrical contact formed on the substrate, wherein the VCSEL includes: a first resonating cavity having first and second mirrors, at least one of which partially transmits light incident on that mirror, wherein the first second mirrors are electrically conductive. A first layer is between the first mirror and the second mirror and has a first aperture that restricts the path of current flow. A second layer is between the first layer and the second mirror and also restricts the electrical current path. A multiple-quantum-well (MQW) structure is between the first mirror and the second mirror, wherein the first and second apertures act together to define a path geometry of the current through the MQW structure.

Claim (Index 32):
The apparatus of  claim 30 , wherein at least one of the first and second mirror structures comprises a graded spacer layer between at least one pair of adjacent alternating layers, the graded spacer layer formed such that aluminum and gallium distributions of the graded spacer layer is monotonically mole-fraction graded over a thickness of the graded spacer layer to match the gallium content in the adjacent alternating layers.
