THE OBJECTIVE OF THIS ONE YEAR SEEDLING PROJECT IS TO ESTABLISH THE ROADMAP TO EFFICIENT TWOPHOTON DEVICES VIA FOUR SYSTEMATIC STEPS (SEE APPROACH) THAT UTILIZE III-NITRIDE SEMICONDUCTOR BASED 2D NANOSHEETS GAIN MEDIA TOGETHER IN HIGH Q MICROCAVITIES. THIS EFFORT WILL PURSUE THE EPITAXY, NANOFABRICATION, MODELING, AND CHARACTERIZATION OF THE NANO-BEAM ARCHITECTURES.
