Abstract:The intention of this work is to discuss and report on our research on nonpolar laser structures grown on bulk GaN crystal substrates along the (1120) nonpolar direction. The main advantages of such nonpolar structures are related to the elimination of the built-in electric fields present in commonly used systems grown along the polar (0001) axis of nitride crystals. We demonstrated the optically pumped laser action on separate confinement heterostructures. Laser action is clearly shown by spontaneous emission… Show more
