摘要

提出了两种基于芯径失配结构的Mach-Zehnder干涉仪，并对其曲率测量进行了实验研究。感测配置包括输入SMF、在两个mmf之间拼接的一段SMF和输出SMF。所提出的传感器在弯曲时产生干涉图案，引起波长偏移。在本文中，mmf采用了两种长度:3mm和4mm。

Mach-Zehnder Interferometer Based on Core Diameter Mismatch Structures for Curvature Measurement

Two Mach-Zehnder Interferometers based on Core Diameter Mismatch structures are proposed and experimentally investigated for curvature measurement. The sensing configuration consists of an input SMF, a section of SMF spliced between two MMFs and an output SMF. The proposed sensor generates interference patterns when it is bent, causing wavelength shifts. In this paper two lengths are used for the MMFs: 3mm and 4mm.
