Abstract
In some implementations, an emitter device includes a substrate layer and epitaxial layers on the substrate layer. The epitaxial layers may include a first mirror, a second mirror, and an active layer between the first mirror and the second mirror. The epitaxial layers may include at least one oxidation layer including a first oxidized region and a second oxidized region separate from the first oxidized region. The first oxidized region and the second oxidized region may be configured to provide a strain on the epitaxial layers that is radially asymmetric. The epitaxial layers may include a set of oxidation trenches in the set of epitaxial layers to expose the at least one oxidation layer.
