摘要
对基于微纳光纤倏逝场效应气体传感器的研究进展进行了综述,同时也阐述了其原理及面临的问题。着重介绍了3 种微纳光纤气体传感器,包括直接基于微纳光纤倏逝场效应气体传感器、微纳光纤表面涂覆敏感薄膜的气体传感器和微纳光纤与其他光学微结构相结合的气体传感器。虽然,这些研究取得了一些成果,但还面临诸多问题和挑战。相信随着研究的不断深入,基于微纳光纤倏逝场效应气体传感器仍有可能凭借其独特的性能优势成为现存气体传感器的有力竞争者。
Abstract
The research progresses of the gas sensors based on microfiber evanescent field effects are summarized. Meanwhile, the sensing principle and faced problems are explained. The research progresses of three kind structures gas sensors based on microfiber evanescent field effects, such as just depending on microfiber evanescent field effects, coating sensitive film on the microfiber surface, and combing with other optical microstructure, are focused. Although some research results have been achieved, many problems and challenges are facing. We believe that with developing of the research, owing to their unique performance advantages, the gas sensors based on the microfiber evanescent field effects are still possible to become a strong competitor for the existing gas sensors.
