Abstract
A vertical cavity laser includes an optical cavity adjacent to a first mirror, the optical cavity having a semiconductor portion and a dielectric spacer layer. A dielectric DBR is deposited adjacent to the dielectric spacer layer. The interface between the semiconductor portion of the optical cavity and the dielectric spacer layer is advantageously located at or near a null in the optical standing wave intensity pattern of the vertical cavity laser to reduce the losses or scattering associated with that interface.
