Abstract
An (SOA) system includes a tunable VCSEL laser with one or more active regions having quantum wells and barriers. The one or more 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 junctions (TJ), one or more apertures 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, the VCSEL having an HCG grading. At least one of an ASIC and driver controller coupled to the VCSEL laser, the ASIC monitoring an output of a light pulse over wavelength.
