Abstract
A vertical cavity surface emitting laser (VCSEL) may include a substrate layer, epitaxial layers on the substrate layer, and angled reflectors configured to receive an optical beam emitted toward a bottom surface of the VCSEL and redirect the optical beam through an exit window in a top surface of the VCSEL. In some implementations, the angled reflectors may be formed in the substrate layer. Additionally, or alternatively, the VCSEL may include molded optics, where the molded optics include the angled reflectors. In some implementations, the exit window may include an integrated lens.
