Abstract :
In this study we report the growth, fabrication and packaging of AlGaN-based light emitting diodes (LEDs) operating at 250 nm for space application [1]. The device fabrication and packaging processes were optimized to ensure a reliable optical fibre coupling. Electrical and optical characterization is presented and discussed; in particular a four-fold increase of the integrated ultraviolet power is demonstrated compared with a non-optimized device. A potential expansion of this approach to InAlN-based devices will also be discussed.
