We review our recent results on GaN based optoelectronic devices, which include InGaN-AlGaN Light Emitting Diodes (LEDs), GaN photoconductive, Schottky barrier, and p-n junction ultraviolet detectors, and optoelectronic AlGaN-GaN Heterostructure Field Effect Transistors. GaN-based optoelectronic devices cover a wide spectral range and demonstrate visible blind operation. A high quality of the epitaxial layers, the recent development of high performance GaN-based heterostructure field effect transistors, and transparent substrates make this material system uniquely suited for optoelectronic integrated circuits operating in visible and ultraviolet range.
