Owing to its wide (3.4 eV) and direct-tunable band gap, gallium nitride (GaN) is an excellent material platform to make UV photo detectors. GaN is also stable in radiation-rich and high-temperature environments, which makes photo detectors fabricated using this material useful for in-situ flame detection and combustion monitoring. In this paper, we use a GaN photo detector to measure ultraviolet (UV) emissions from a hybrid rocket motor igniter plume. The GaN photo detector, built at the…

Optical sensors based on III-nitride photodetectors for flame sensing and combustion monitoring.
TLDR
UV-visible P-InGaN/GaN multiple quantum well-N photodiodes with 15-18 mm2 areas were fabricated to conduct OH* and CH* CL detection without external filters and an exponential association dependence between the optical OH*/CH* CL signals and the gas/air ratios was found.
