摘　　要：高灵敏度的光传感技术在工业过程控制、环境监测、食品安全、国家安全等领域具有重要的应用。随着平面光集成制备技术的发展,光传感器件也从研究开发光纤传感器拓展到便于集成的平面波导光传感器,特别是采用多孔、易掺杂的溶胶-凝胶材料作为化学、生物医学探测的光传感媒介。综述了平面波导光传感器的研究现状与发展趋势,讨论了器件的光传感原理与结构,介绍了其在化学、生物医学、环境检测等方面的应用。High-sensitive optical sensing technology has been applied in various areas, such as industrial process control, environmental monitoring, food safety and even national security. Benefited from the development of planar optical integration technology, optical sensors are developed from using optical fiber as platform to using easy-integrated planar waveguides, especially using porous or doped sol-gel materials as the optical media for chemical and biomedical sensing. The development of planar waveguide sensors is reviewed, followed by the sensing principle and structures of sensor devices. Application in chemistry, biomedicine, environment protecting is introduced. Development trend of sensor devices is also discussed.
