Abstract
An apparatus is provided to receive a three dimensional (3D) map of at least a part of a body of a user. A light emitting device is included with tunable VCSEL laser with one or more active regions having quantum wells and barriers. The active regions are surrounded by one or more p-n junctions. The one or more active regions can include a selected shape structure one or more tunnel junction (TJ)provided. One or more apertures are provided with the selected shape structure. One or more buried tunnel junctions (BTJ) or oxide confine the apertures, additional TJ's, planar structures and or additional BTJ's created during a regrowth process that is independent of a first growth process. A VCSEL output is determined in response to an application of the VCSEL laser. The VCSEL laser includes an HCG grating and a bottom DBR. A user monitoring deviceincludes the VCSEL laser. A user monitoring device that includes the VCSEL laser. The light emitting device is included in a camera of a communication device.
