“…The spectrum of the second FBG, the one used in the spectral and polarization analysis, is reported in Figure 1b. The fiber used in this work presents a core doped with a random pattern of nanoparticles whose composition is based on MgO [17,19]. The fiber, designed to improve the efficiency of C-band optical amplifier (wavelengths from 1530 to 1565 nm), presents an additional doping of erbium in the core.…”

“…More recently, Beisenova et al [16] have obtained a 36.5 dB scattering increment by using a MgO-nanoparticle-doped (MgO-NP) fiber as sensing medium. This setup has also been used to design a scattering-level multiplexing [16,17], a new domain of multiplexing where the diversity is given by the scattering level at each sensing point. While the first two methods are characterized by a specific fabrication at one specific sensing point, the third method provides an optical fiber that can be spooled and spliced directly to a SMF, making the operation of building a multi-fiber sensing network much simpler.…”

“…The possibility to increase the scattering of a fiber is intriguing in distributed sensing, particularly using optical backscatter reflectometry (OBR) [18], whereas the analyzer detects the distributed Rayleigh scattering backreflection occurring in each region of the fiber. In such system, by increasing the Rayleigh scattering a larger signal at the analyzer can be obtained [13][14][15][16][17], over 3-4 orders of magnitude larger when properly tuning scattering properties.…”

The characterization of Fiber Bragg Grating (FBG) sensors on a high-scattering fiber, having the core doped with MgO nanoparticles for polarization-dependent temperature sensing is reported. The fiber has a scattering level 37.2 dB higher than a single-mode fiber. FBGs have been inscribed by mean of a near-infrared femtosecond laser and a phase mask, with Bragg wavelength around 1552 nm. The characterization shows a thermal sensitivity of 11.45 pm/°C. A polarization-selective thermal behavior has been obtained, with sensitivity of 11.53 pm/°C for the perpendicular polarization (S) and 11.08 pm/°C for the parallel polarization (P), thus having 4.0% different sensitivity between the two polarizations. The results show the inscription of high-reflectivity FBGs onto a fiber core doped with nanoparticles, with the possibility of having reflectors into a fiber with tailored Rayleigh scattering properties.

“…A setup for multiplexed distributed optical fiber sensors, which are capable to measure temperature in the range of up to 140 • C (of interest for biomedical applications such as thermo-therapy) with a spatial resolution of 2.5 mm over the several fibers simultaneously, has been reported in [197]. Finally, this approach is also applicable for strain measurements and 3D shape sensing [198,199].…”

For years, scientists have been looking for different techniques to make glasses perfect: fully amorphous and ideally homogeneous. Meanwhile, recent advances in the development of particle-containing glasses (PCG), defined in this paper as glass-ceramics, glasses doped with metallic nanoparticles, and phase-separated glasses show that these "imperfect" glasses can result in better optical materials if particles of desired chemistry, size, and shape are present in the glass. It has been shown that PCGs can be used for the fabrication of nanostructured fibers-a novel class of media for fiber optics. These unique optical fibers are able to outperform their traditional glass counterparts in terms of available emission spectral range, quantum efficiency, non-linear properties, fabricated sensors sensitivity, and other parameters. Being rather special, nanostructured fibers require new, unconventional solutions on the materials used, fabrication, and characterization techniques, limiting the use of these novel materials. This work overviews practical aspects and progress in the fabrication and characterization methods of the particle-containing glasses with particular attention to nanostructured fibers made of these materials. A review of the recent achievements shows that current technologies allow producing high-optical quality PCG-fibers of different types, and the unique optical properties of these nanostructured fibers make them prospective for applications in lasers, optical communications, medicine, lighting, and other areas of science and industry.Made of glass, optical fibers inherited all positive and negative properties of this material. Glasses are easy and inexpensive to produce on any scale and in any shape, they can possess high chemical stability and mechanical strength, and have high transparency. However, they could hardly compete, for example, with crystalline materials in thermal conductivity, or rare-earth elements' absorption, emission cross-sections, and available transparency range. Recent advances in glass science showed that properties of this material can be significantly improved if some additional phases are formed or impregnated in the glass. In particular, advances have been achieved in the development of particle-containing glasses: glass-ceramic materials, glasses doped with metallic nanoparticles, and phase-separated glasses. To date, these particle-containing glasses have become quite common and actively used in case of the bulk materials, but are still rather new for fiber optics.The purpose of this review is to summarize recent advances in the fabrication of structured fibers made of particle-containing glasses, their potential benefits, their actual properties, and their potential applications. The review covers three types of particle-containing glasses (PCG): crystalline dielectric particles, i.e., glass-ceramics; metallic nanoparticles (MeNPs); and dielectric amorphous particles, i.e., phase-separated glasses.First, we consider properties of the PCG bulk materials, their potenti...
