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 31):
The apparatus of  claim 28 , 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.
