Electron intersubband transitions in quantum wells are the primary physicalmechanism for the generation and detection of mid- and far-infrared(terahertz) radiation as used in quantum cascade lasers and quantum wellinfrared photodetectors. This range of wavelengths has applications inmolecular sensing, atmospheric and pollution monitoring security, medical imaging and secure communications. Thescientific community is now looking at other material systems for evenbroader wavelength coverage and high temperature operation as well asintersublevel transitions in quantum dots for improved device performance: allof these aspects are discussed in the biennial International Conference onIntersubband Transitions in Quantum Wells (ITQW) which the authors havefought hard to secure for the U.K. in September 2007 after losing out on two previous occasions to Switzerland in 2003 and Cape Cod in 2005. Theauthors seek modest funding from the EPSRC to help support this prominentevent and showcase the leading U.K. work in this research field.

量子威尔斯中的电子子带间跃迁是产生和探测中红外和远红外（太赫兹）辐射的主要物理机制，如量子级联激光器和量子阱红外光电探测器。该波长范围可应用于分子传感、大气和污染监测安全、医学成像和安全通信。科学界现在正在寻找其他材料系统，以获得更宽的波长覆盖范围和高温操作，以及量子点中的子能级间跃迁，以改善器件性能：所有这些方面都在两年一度的量子威尔斯子带间跃迁国际会议（ITQW）上讨论，作者为英国努力争取。2007年9月，在2003年和2005年分别输给瑞士和科德角之后。作者从EPSRC寻求适度的资金，以帮助支持这一事件，并展示领先的英国。在这个研究领域工作。
