本文介绍了一种光纤折射率传感器的设计与制作。该新概念采用长周期光纤光栅（LPG）在单模光纤的金涂层尖端实现单包层模式的表面等离子体共振（SPR）。该传感器结合了高水平的灵敏度、小型化的传感区域和简单的基于强度的询问，旨在使用便携式护理点设备或高度集成的芯片实验室系统进行生物传感。
This paper presents the design and fabrication of a fiber-optic refractive index (RI) sensor. The novel concept employs a long-period fiber grating (LPG) to achieve surface plasmon resonance (SPR) of a single cladding mode at the gold-coated tip of a single-mode fiber. The sensor combines a high level of sensitivity, a miniaturized sensing area and simple intensity-based interrogation, and is intended for biosensing using portable point-of-care devices or highly integrated lab-on-chip systems.
