Abstract
A radiation source includes a semiconductor substrate, an array of vertical-cavity surface-emitting lasers (VCSELs) formed on the substrate, which are configured to emit optical radiation, and a transparent crystalline layer formed over the array of VCSELs. The transparent crystalline layer has an outer surface configured to diffuse the radiation emitted by the VCSELs.
