“…In metastable liquids (glasses), this process can takes place also below the liquidus temperature on cooling as well as on heating through two main mechanisms: spinodal and binodal [1]. In this latter case the development of the new liquid phase goes on by nucleation and subsequent growth of the nuclei to droplets, the size of which may be controlled by a proper heat treatment [1,2]. In our opinion, the phase separation can be considered a powerful tool to make functional glassy materials especially in the field of optical applications.…”

“…3 Recently, optical functional glass, such as rare-earth-ion-containing glass microshpere is being made by liquid-liquid phase separation. 4 However, this phenomenon is accompanied by substance movement in the liquid state, and it tends to be influenced by gravity compared with phase separation which takes place in the solid state.…”

“…The higher scattering could provide significant benefits for specific light propagation cases, illumination, or random lasing applications. At the same time, the dopants present in the host glass can be redistributed among the phases, resulting, for example, in a higher concentration of the REE in one of the phases [16]. This can induce additional concentration losses, as it was shown, for example, for Er 3+ in alkali borosilicate glasses [17] and enhancement of the up-conversion luminescence, which was demonstrated recently for fluorosilicate glasses [18].…”

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...
