1. A method of manufacturing, the method comprising:
coupling a first surface of a light-emitter substrate to a reference surface of a carrier substrate;
registering a mold structure with respect to the reference surface of the carrier substrate;
forming an optical material over at least a portion of the light-emitter substrate using the mold structure registered with respect to the reference surface, wherein the optical material is shaped according to a shape of the mold structure, and wherein the optical material comprises at least one registration feature; and
coupling an optical lens element to the optical material such that the optical lens element is registered to the at least one registration feature and an optical axis of the optical lens element extends through the optical material to the light-emitter substrate.
