We review fiber-based multimode interference (MMI) devices with a particular focus on
optical fiber-based sensing applications. The present review complements a recently …

The unique structural characteristic of no-core fiber (NCF) have extended the sensing
applications based on multimode interference self-imaging, evanescent wave absorption …

We have investigated the influence of multimode fiber core (MMFC) diameters and lengths
on the sensitivity of an SMS fiber based refractometer. We show that the MMFC diameter has …

We report a simple fiber sensor for measurement of high temperature with high sensitivity.
The sensing head is a multimode-single mode-multimode (MM-SM-MM) fiber configuration …

This paper presents an investigation on a single-mode–multimode–single-mode fiber
structure. A one-way guided-mode propagation analysis for the circular symmetry …

We present a comprehensive study of the strain and temperature-sensing characteristics of
single-mode–multimode–single-mode (SMS) structures based on the modal interference of …

A fiber-optic temperature sensor based on the interference of selective higher-order modes
in circular optical fibers is described. The authors demonstrate that by coupling the LP 01 …

A fiber-optic curvature sensor based on the single-mode-multimode-single-mode (SMS)
fiber structure is developed. Several notches in the transmitted spectrum of the SMS fiber …

A novel design for an all-fiber bandpass filter based on a multimode interference reimaging
phenomenon is presented. The filter has achieved low insertion loss with adequate …

An in-fiber Mach–Zehnder Interferometer (MZI), based on hollow core fiber (HCF), for
measuring curvature is fabricated and experimentally demonstrated. The sensing part was …
