Optical Fiber-Based Technologies and Applications

ABSTRACT

Optical fiber-based devices have been widely deployed in recent years.  There are many advantages of using fiber as a sensor. These include electrically-passive operation, light weight, immunity to radio frequency interference and electromagnetic interference, high sensitivity, compact size, corrosion resistance, easily multiplexing and potentially low cost. Several novel fiber-based sensors and technologies developed are presented here, including fiber Bragg grating (FBG) based sensors, photonic crystal fiber (PCF) based sensors, specialty fiber-based sensors and distributed fiber sensing systems. FBGs as instinctive sensors, are ingeniously designed as two-dimensional (2D) tilt sensors, displacement sensors, accelerometers and corrosion sensors here; PCF based evanescent field absorption sensor, PCF induced Mach-Zehnder interferometer and Fabry-Perot refractometer for temperature and refractive index sensing are presented; based on localized surface Plasmon resonant (LSPR) effect, nano-sized fiber tip with gold nanoparticles are demonstrated for live cell index bio-sensing applications.

近年来，基于光纤的器件得到了广泛应用。将光纤用作传感器具有诸多优势，包括无源工作、重量轻、抗射频干扰与电磁干扰、灵敏度高、体积紧凑、耐腐蚀、易于复用以及潜在的低成本等。本文介绍了若干新型光纤传感器与相关技术，包括基于光纤布拉格光栅（FBG）的传感器、基于光子晶体光纤（PCF）的传感器、特种光纤传感器以及分布式光纤传感系统。作为本征型传感器，光纤布拉格光栅在此被巧妙设计为二维倾角传感器、位移传感器、加速度计与腐蚀传感器；介绍了基于光子晶体光纤的倏逝场吸收传感器、光子晶体光纤型马赫—曾德尔干涉仪以及用于温度与折射率传感的法布里—珀罗折射率计；基于局域表面等离子体共振（LSPR）效应，本文展示了修饰金纳米颗粒的纳米级光纤尖端在活细胞指数生物传感中的应用。
