Abstract
A monitoring device system includes a tunable VCSEL laserwith 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 each with a tunnel junction (TJ). 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 a monitoring application of the VCSEL The VCSEL includes an HCG grating and a bottom DBR. A user monitoring device includes the VCSEL laser. A motion detection apparatus detects a user's movement information. The motion detection apparatus and the monitoring system assist to determine one or more of a person's: gestures; sleep information and sleep behavior information, or user respiration information. A cloud based system is in communication with the monitoring device and the motion detection apparatus.
