Abstract

We review fiber-based multimode interference (MMI) devices with a particular focus on optical fiber-based sensing applications. The present review complements a recently published, extensive review where the sensing of conventional physical variables such as refractive index, temperature, displacement, and strain was covered. This review focuses on MMI fiber sensors for nonconventional physical variables, including mechanical, electromagnetic, chemical, and optical, covering around fifteen years of work in the field. Finally, by the end of this paper, we also review some new trends of MMI-based schemes based on polymer fibers, for wavelength-locking applications, for retrieving the thermo-optic coefficient of liquid samples, and for measuring the dynamics of complex fluids.

摘要

我们回顾基于光纤的多模干涉（MMI）器件，特别关注基于光纤的传感应用。本综述补充了最近发表的一篇全面综述，该综述涵盖了对诸如折射率、温度、位移和应变等传统物理变量的传感。本综述聚焦于用于非常规物理变量的MMI光纤传感器，包括机械、电磁、化学和光学变量，涵盖了该领域约十五年的工作。最后，在本文结尾，我们还回顾了基于聚合物光纤的MMI方案的一些新趋势，用于波长锁定应用、获取液体样品的热光系数以及测量复杂流体的动力学。
