Abstract
Disclosed herein are various embodiments for laser arrays that include graphene lens structures located on laser-emitting semiconductor structures. In an example embodiment, an apparatus comprising (1) a laser-emitting epitaxial structure having a front and a back, wherein the laser-emitting epitaxial structure is back-emitting, and (2) a graphene lens structure located on the back of the laser-emitting epitaxial structure. Photolithography processes can be used to deploy the graphene lens structures on the laser structures.
