Extremely efficient light emission is achieved in heteroepitaxial layers of GaN based materials. A photonic device fabricated on GaN regions provides better optical output and reliability. The advantages of AlGaInN system are wide bandgaps, good transport properties, and availability of heterostructures. Packaged switches made from AlGaN can operate at temperatures exceeding 250° centigrade, thereby reducing system complexity. The base resistance of GaN heterojunction bipolar transistors (HBTs) is much lower due to high doping level.
