“…[ 43 ] These effects result not only in the changes on refractive index, polarization, and so on, but also in the change of shape in magnetostrictive materials. Compared with the nonfused POF, the fused POF shows a 30 times higher magnetostriction, [ 44 ] which confirms the possibility of using the fused POFs in optical devices such as an intrinsic magnetic field sensor.…”

This article presents a review of the fuse effect in polymer optical fibers (POFs) and its sensing applications. First, the propagation mechanisms and the characteristics of the POF fuse are discussed, showing that its optical threshold power and propagation velocity are much lower than those of silica fiber fuse. In addition, it is shown that the main unique advantages of the POF fuse are its capability of transmitting optical signal as well as the electrical conductivity of the carbonized oscillatory path created in the fiber core. The physical properties of the fused POF are also described, such as its higher elasticity and stability to external effects. Subsequently, some applications of fused POFs are reviewed, such as temperature, strain, force, and angle sensors with higher sensitivity and stabler operation than those of nonfused POF‐based sensors. Finally, future perspectives on fused POF‐based sensing are discussed, where the magnetic field sensitivity plays an important role in implementing the optical devices. Thus, the unique features of fused POFs can provide a new paradigm for the fuse effect in optical fibers, in which the effect can be intentionally ignited for fabrication of novel in‐fiber devices and sensors with extended capabilities.

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.

“…Optical fibers are part of everyday life, especially in communications, where they are used to convey information. Optical fibers have various advantages: low weight, small radius, high stability, high sensitivity, imperviousness to electromagnetic interference, and a high tolerance for harsh environmental conditions [ 1 , 2 ]. Due to their high sensitivities, optical fibers are widely applied in communications and have also displayed excellent performance in sensing and measurement applications [ 3 ].…”

The influence of the bending radius on the sensitivity of the graphene quantum dots (GQDs)-coated probe is experimentally investigated for a U-shaped probe. The fiber is bent into a U shape using the optic fiber flame heating method, and the optic fiber is enclosed in a glass tube to increase the stability of the probe. The surface of the U-shaped optical fiber was coated with electrospun fibers formed via electrospinning. Polymer materials doped with GQDs are applied to U-shaped optical fiber as humidity sensors. Graphene quantum dot nanofibers on the U-shaped optical fiber sensor to form a network structure of graphene quantum dots U-shape fiber sensor (GQDUS). The polymer network structure absorbs water molecules, which in turn affects the bending radius of the optical fiber, and changes the optical fiber spectrum. Graphene quantum dots provide optical enhancement benefits, which in turn increase the sensitivity of fiber optic sensors. The spectra monitoring system consists of an optical spectrum analyzer (OSA) and an amplified spontaneous emission (ASE). This system can be used to detect humidity changes between 20% RH and 80% RH in the chamber. Our results indicate promising applications for quantum dots probe sensors from electrospun nanofibers increasing sensitive environmental monitoring. As such, it could be of substantial value in optical sensors detection.
