Few-mode fibers (FMFs) have found applications in optical communications and sensors
with attractive features that standard single mode fiber (SSMF) do not possess. We report …

Recently there is a growing interest in develo** few-mode fiber (FMF) based distributed
sensors, which can attain higher spatial resolution and sensitivity compared with the …

We propose a unique few-mode fiber (FMF)-based multi-parameter optical-fiber sensor for
distributed measurement of temperature and strain. We launch a pump and a probe signal …

Abstract Space division multiplexing (SDM) has attracted considerable attention within the
fiber optics communication community as a very promising approach to significantly …

Brillouin scattering is a dominant inelastic scattering observed in optical fibers, where the
energy and momentum transfer between photons and acoustic phonons takes place …

Numerical and experimental results on stimulated Brillouin scattering (SBS) in a graded-
index multimode silica fiber are reported. The Brillouin Gain Spectrum (BGS) is shown to …

A distributed optical fiber dynamic strain sensor also known as a distributed acoustic sensor
(DAS) based on two-mode fiber is demonstrated. By using φ-OTDR interrogation technique …

The effect of annealing is experimentally studied for a fused silica, fully distributed fiber optic
sensor based on the pulse pre-pump Brillouin optical time domain analysis (PPP-BOTDA) …

In this work, we demonstrate the measurement of the Brillouin gain spectra of vector modes
in a few-mode fiber for the first time using a simple heterodyne detection technique. A …

A complete theoretical model on the stimulated Brillouin scattering (SBS) for multi-mode
fibers (MMF) is developed by solving the optical-acoustic coupling wave equations. It shows …
