Abstract
We report the demonstration of ultra-high Q (>2.5 ×106) ring resonators made of fully-etched single crystal aluminum nitride waveguides on sapphire substrate, at 1550nm wavelength, enabling a new class of compact classical/quantum photonic devices.

Abstract
Abstract
We have studied the epitaxy and fabrication of AlGaN nanocrystal LEDs in the UV-B and UV-C bands. By coupling with epitaxial Al layers, an electrically pumped plasmonic UV laser is demonstrated for the first time.
