摘要/Abstract

摘要： 随着光纤微加工技术的发展，侧边抛磨光纤（side polished fiber，SPF）在光纤传感器领域开辟了一个新纪元。在普通通信光纤的基础上，通过完全或者部分去除一段长度的光纤包层形成传输光场的“泄漏窗口”，利用光场与物质相互作用来激发、控制、探测光纤纤芯中的传输光场，从而制备了各种基于倏逝场的传感器。优化光纤的抛磨参数和导模特性是实现高性能光纤传感器的关键。侧边抛磨光纤具有可靠的机械性能和极小的插入损耗、偏振相关损耗，使其成为研究“光纤上实验室”的优质平台。本文综述了基于侧边抛磨光纤传感器的原理、分类、研究进展和应用领域。

Abstract: With the development of optical fiber microfabrication technology, side polished fiber (SPF) has opened up a new era in fiber optic sensors. On the basis of ordinary communication fiber, the "leakage window" of the transmission light field is formed by completely or partially removing a length of fiber cladding. The light-matter interaction is used to excite, control, and detect the transmission light field in the fiber core to fabricate various sensors based on evanescent field. Optimizing the polishing parameters and guiding characteristics of the optical fiber is the key to realizing high-performance fiber optic sensors. The SPF has reliable mechanical properties, minimal insertion loss and polarization-dependent loss, making it a high-quality platform for research on the "lab on fiber". This article reviews the principle, classification, research progress, and application prospects of the SPF-based fiber optic sensors.

Key words: side polished fiber (SPF), optical fiber sensor, optical fiber microfabrication technology, evanescent field, lab on fiber
