UV illumination effects on AlGaN/GaN HEMTs for tunable RF oscillators

2021 IEEE RADIO AND WIRELESS SYMPOSIUM (RWS), pp. 168–170.

By: S. Stein n, M. Robbins n, P. Reddy*, R. Collazo n & S. Pavlidis n

author keywords: AlGaN/GaN HEMTs; Optical Control; Illumination Effects; Oscillator
TL;DR: This is the first investigation of AlGaN/GaN HEMTs as optically-controlled microwave semiconductor devices for use in next-generation, high-power microwave photonics systems and measures show a modest change in S21 in the presence of UV illumination that induces internal photoconductive and photovoltaic effects.
