Abstract
A VCSEL with undoped top mirror. The VCSEL is formed from an epitaxial structure deposited on a substrate, and a periodically doped conduction layer is coupled to the undoped top minor. A periodically doped spacer layer is coupled to an active region. An undoped bottom minor coupled to the periodically doped spacer layer. A first intracavity contact is coupled to the periodically doped conduction layer and a second intracavity contact is coupled to the periodically doped spacer layer.
