Abstract
A VCSEL illuminator package includes one or more VCSELs in a substrate. The one or more VCSELs are operable to generate a VCSEL output radiation beam. An encapsulant covers the one or more VCSELs, and an optical structure is integrated in the encapsulant. The optical structure is disposed in a path of the VCSEL output radiation beam and is operable to change at least one of a propagation characteristic or intensity distribution of the VCSEL output radiation beam exiting the encapsulant.
