Abstract

A compact highly sensitive microfiber coupler based reflective micro-force sensor is presented. The device is fabricated by fusing two twisted optical fibers and then connecting two of the pigtails to form a Sagnac loop. The sensor has a high force sensitivity of ~3754 nm/N which is three orders of magnitude larger than traditional optical fiber force sensors, and a low detection limit of ~1.6 µN. The good repeatability is also shown in this paper.

摘要

本文提出了一种基于紧凑型高灵敏度微光纤耦合器的反射式微力传感器。该器件通过熔接两根扭曲的光纤，然后连接两根尾纤形成一个萨格纳克环来制造。该传感器具有约3754 nm/N的高力灵敏度，比传统光纤力传感器高三个数量级，检测下限约为1.6 µN。本文还展示了其良好的重复性。
