摘　　要：本文介绍了本课题组在光纤微流激光传感器和无源光纤微流传感器两方面的研究进展。光纤微流激光传感器利用光纤微流激光的输出变化来探测生化参数的改变。光纤截面作为环形微腔形成光反馈,增强了腔内光子和待测物质的相互作用,从而提高了微流激光的传感灵敏度。此外,光纤尺寸均匀,易低成本、批量制作光纤微腔,可制备高重复性或一次性使用的光纤微流激光。本文还介绍了基于光力/光热效应的无源光纤微流传感器。该类传感器利用光产生的力学或热学效应对微流体进行温度、流速、浓度传感,具有灵活性高、集成度好、多功能、可重构等特点。In this mini-review,recent advances in the fiber optofluidic lasers and passive fiber optofluidic sensors are introduced.Fiber optofluidic laser can detect the biochemical changes using its laser output as a sensing signal.The cross-section of fiber can be used as a microcavity,providing optical feedback.The microcavity enhances the light-matter interaction,thus increasing the sensitivity.Furthermore,the geometry of optical fibers is uniform,easy to be mass produced with low cost,can be used to realize highly reproducible and disposable optofluidic laser.Passive fiber optofluidic sensors are also introduced based on the laser induced force and photo-thermal effects,which is flexible,easy to be integrated,multi-functional and reconfigurable.
