Abstract

We present deep UV light-emitting diodes and photodetectors based on high Al-composition AlGaN. We have obtained very short wavelength UV LEDs (<255 nm) with milliwatt level optical output powers, based on an AlGaN multiple-quantum well active region. Solar-blind photodetectors have also been fabricated with quantum efficiencies in excess of 70%. Based on these photodetectors, focal plane arrays have been fabricated.
