Integrated self-pumped optical frequency conversion and generation in semiconductor waveguides.

中红外气体检测在环境监测、临床分析、生命科学、安全和食品工业等领域变得越来越重要。然而，目前还没有紧凑的、室温的、可调谐的光源可随时用于光谱的2-5微米部分。目前基于量子级联激光器和铅盐激光器的方法提供有限的可调谐或需要冷却。在这一应用中，我们提出了一种实现片上，电泵浦，可调的中红外光源的方案。该光源将由集成光学参量振荡器和半导体泵浦激光器单片集成组成。该项目将与格拉斯哥大学合作进行。格拉斯哥大学的研究人员率先在一块芯片上集成了有源和无源组件。

Mid infrared gas detection has become increasingly important in areas such as environmental monitoring, clinical analysis, life sciences, security and the food industry. However at present there are no compact, room temperature and tunable sources readily available for the 2 - 5 micron part of the spectrum. Current approaches based on quantum cascade lasers and lead salt lasers offer limited tunability or require cooling.In this application we present a proposal for realizing an on-chip, electrically pumped, tunable mid IR source. The source will consist of an integrated optical parametric oscillator monolithically integrated with a semiconductor pump laser.The project will be carried out in collaboration with the University of Glasgow. Researchers at the University of Glasgow have pioneered the ability to monolithically integrate active and passive components on to a single chip.
