Photonic Crystal Enhanced Wavelength Selective, Multi-Colour Quantum Dot Infrared Photodetectors

光子晶体增强型量子点红外探测器是将纳米技术与材料科学、光学相结合而发展起来的新一代探测器。这不仅可以提高探测器的性能，而且这种结构现在可以探测到所需波长周围的窄波段，具有多色探测能力。该项目开发的技术预计将吸引工业和政府机构的兴趣。它将广泛应用于家庭、制造业和采矿业、环境和污染监测、国防和国家安全。应用包括光谱成像、遥感、环境/污染监测、有毒气体和生物有害物质检测。

Photonic crystal enhanced quantum dot infrared photodetectors are a new generation of detectors developed from integrating nanotechnology with material science and optics. This would not only enhance the detector performance but the structure will now detect a narrow band around the desired wavelength with multi-colour detectivity. The technology developed in this project is anticipated to attract interest from the industries and government agencies. It will be pervasive for use at home, in the manufacturing and mining industry, environmental and pollution monitoring, defence and national security. Applications include spectral imaging, remote sensing, environmental/pollution monitoring, toxic gas and bio-hazardous material detection.
