Abstract
An apparatus is provided to receive a three-dimensional (3D) map of at least a part of a body of a user. A tunable VCSEL laser has one or more active regions having quantum wells and barriers, the active regions surrounded by one or more p-n junctions, the one or more active regions can include a selected shape structure, as well as one or more tunnel junctions (TJ), one or more apertures are provided with the selected shape structure, one or more buried tunnel junctions (BTJ) or oxide confine apertured, additional TJ's, planar structures and or additional BTJ's created during a regrowth process that is independent of a first growth process with a VCSEL output. Optics collect and focus light emitted by the output of the VCSEL laser defining a baseline light pattern having a given pitch, corresponding to a two-dimensional pattern of the optical emitters on a substrate, producing and projecting multiple overlapping replicas of the baseline light pattern with a composite pattern density that is finer than the pitch of the baseline light pattern.
