Abstract
A tunable VCSEL includes a top DBR; a bottom DBR; a plurality of successive active regions with tunnel junctions TJ's, each active region includes quantum wells and barriers surrounded by one or more p-n junctions; and a grating at a top of the top DBR.
Claims21
A light emitting device, comprising:
- a tunable VCSEL laser with 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 determined in response to a monitoring application of the VCSEL, the VCSEL having an HCG grating and a bottom DBR;
- and
- a deformable grating positioned at a top of the VCSEL.
The system of claim 13, wherein the VCSEL laser can deploy multiple tunnel junctions to enhance the output of the VCSEL laser.
1 The system of claim 1, wherein the VCSEL laser includes a dielectric coating.
