Stopped light for photo-sensing
We propose a high sensitivity photodetection tool at near-infrared frequencies, based on a novel principle of slowed- and stopped- light in chirped photonic micro/nano- structures. The main goal is to a) substantially increase the photodetection efficiency due to increased intensity of stopped light; b) to provide the chromatic resolution of photodetection, sins the photons of different color stop at different positions along the photonic crystal. Technically concept is to be used to improve the performance of for obscured and night vision devices working at near -infrared frequencies. The consortium brings together the expertise of groups on stopped light (conceptual part), see the Figure, micro/nano-fabrication of photonic artificial materials (photonic crystal part), and photo-sensitive materials (photo-detection part), i.e. covering all basic skills to attain the proposal.
