用于光谱学的片上中红外和太赫兹频率梳

On-chip mid-infrared and THz frequency combs for spectroscopy

Giacomo Scalari, Jérôme Faist, Nathalie Picqué

摘要:

频率梳已经彻底改变了时间和频率计量学,并且近年来,高度紧凑甚至片上的新频率梳激光器已经在电磁波谱的中红外和THz区域中得到展示。新兴的技术包括电泵浦量子和带间级联半导体器件,以及高品质因数微谐振器。在这篇客座社论中,作者总结了该领域的最新进展,快速宽带光谱的潜力,以及在分子气体传感中使用的挑战和前景。

英文摘要:

Frequency combs have revolutionized time and frequency metrology and in recent years, new frequency comb lasers that are highly compact or even on-chip have been demonstrated in the mid-infrared and THz regions of the electromagnetic spectrum. The emerging technologies include electrically pumped quantum and interband cascade semiconductor devices, as well as high-quality factor microresonators. In this guest editorial, the authors summarize recent advances in the field, the potential for rapid broadband spectroscopy, as well as the challenges and prospects for use in molecular gas sensing.
