Abstract: A laser assembly, such as a flood illuminator, has laser (e.g., VCSEL) emitters on a substrate configured to emit optical signals. An optic structure of optically transparent material, such as a polymer, is formed directly on the substrate, and micro-optic elements are nano-imprinted on the optic structure. The micro-optic elements are arranged in optical communication with the optical signals emitted from the laser emitters to perform field mapping or other optical functions. The laser emitters are on the same surface of the substrate as the optic structure along with electrical contacts so forming the optic structure involves covering the electrical contacts with a protective layer, dispensing a polymer for the optic structure, cutting away portions of the optic structure, removing the remaining protective layer, and exposing the electrical contacts.
