A dual-parameter fiber sensor based on few-mode fiber and fiber Bragg grating for strain and temperature sensing

, 2020
An optical fiber temperature and strain fiber sensor based on the few-mode fiber (FMF) and the fiber Bragg grating (FBG) is proposed and demonstrated. The sensor unit is fabricated by a length of FMF offset splicing with one section of single-mode fiber (

Few-mode fibers for mode-division multiplexing

2013 IEEE Photonics Society Summer Topical Meeting Series, 2013
The design of few-mode fibers will be discussed from the point of view of key attributes and fundamental limitations. We will consider the maximum number of modes that might be supported in a practical fiber.

Highly Sensitive Magnetic Field Sensor Based on Few-Mode Fiber Interferometry

IEEE Sensors Journal
This article proposes an all-fiber Mach–Zehnder interferometer (MZI) magnetic field sensor based on few-mode fiber (FMF) and hollow-core fiber (HCF). The proposed SMF-FMF-HCF-SMF (SFHS) structure is achieved by fusion splicing FMF and HCF between two ...

Few-Mode Fiber Devices

Optical Fiber Sensors, 1988
Few-mode fibers provide a number of independent channels in a single strand of optical fiber. Therefore they have potential for increasing channel capacity and data throughput, stabilizing coherent systems, simplifying and miniaturizing fiber optic circuits, and multiplying the number of functions and operations which can be performed.

Mode measurement of few-mode fibers by mode-frequency mapping

Optics Letters, 2018
Since few-mode fibers (FMFs) have great potential as the new transmission media for optical communications, the ability to distinguish different fiber modes is essential. Most of the traditional schemes do not yield phase information, or are limited by beam size and mechanical requirements.

Orthogonality breaking through few-mode optical fiber

Applied Optics, 2016
Polarization sensing and imaging through optical fibers is a technological challenge motivated by promising applications for in vivo, in situ polarimetric endoscopy for biomedical diagnosis. Among the recent approaches proposed to solve this issue, the depolarization/dichroism sensing by polarization orthogonality breaking (DSOB) technique was shown to
