“…One approach is to prepare NCs, then to pre-mix them with the glass powder and, finally, to melt the batch into a hybrid glass. However, as explained in [76,77], an insufficient dispersion of the NCs had been obtained using this technique [76]. Dissolution of the nano-/micro-scale crystals or a decrease in the transmission of the resulting glass was reported in [78][79][80][81][82].…”

Applications involving optical fibers have grown considerably in recent years with intense levels of research having been focused on the development of not only new generations of optical fiber materials and designs, but also on new processes for their preparation. In this paper, we review the latest developments in advanced materials for optical fibers ranging from silica, to semi-conductors, to particle-containing glasses, to chalcogenides and also in process-related innovations.

Cr2+‐doped materials with mid‐infrared (Mid‐IR) broadband luminescence are of fundamental importance for various applications, such as solid‐state lasers technology, biolabeling, optical telecommunication, and solar energy management. Especially, Cr2+‐doped glass has been considered as one of important material candidates. The major challenge is the precipitation of crystals doped with Cr2+ ions in glass. So, “crystals in glass composite” is an effective method to solve this issue. Here, we describe a ZnS:Cr2+ in borophosphate glass composite (CZPB) which exhibits Mid‐IR luminescence in the region from 1700 to 2900 nm with the full width at half maximum (FWHM) of about 690 nm. In addition, the materials can also be fabricated into fiber without obvious change in the characteristic luminescence band. The results provide new opportunities for the construction of the broadband fiber light source operating at Mid‐IR waveband region.

“…The other method proposed by Mironov et al consists of the following steps: (i) prepare II-VI ChG powders by mechanical grinding to micrometer scale, (ii) prepare chalcogenide glasses (ChGs, e.g., As 2 S 3 ) using a conventional melt-quenching method, (iii) mix the II-VI micropowders with the ChGs, and (iv) synthesize the II-VI microcrystals embedded ChG glass preforms for fiber drawing using the conventional technique. 6,7 This method is capable of producing fibers typically of a few meters in length, and thanks to the refractive index matching between the II-VI crystals and ChGs, the optical losses can be restricted to relatively low levels (2~4 dBÁm À1 ) which is an advantage for practical applications. 8 However, the relatively large size of the embedded II-VI microcrystals (comparable to the pumping and lasing wavelengths) would cause Mie scattering in laser applications.…”

Chalcogenide glasses (ChGs) containing II‐VI chalcogenide (ChG) nanocrystals such as ZnS/Se have recently been intensively studied as promising mid‐infrared nonlinear optics and laser materials, yet preparation of pure‐phase II‐VI nanocrystals embedded in ChGs via controlled crystallization is still very challenging. In this study, a new system of ChGs and glass ceramics (GCs), viz., (100−x)As2S3–xZnSe (x = 0 ~ 30 mol%), is synthesized, and its physical and optical properties including density, molar volume, microhardness, glass transition temperature, glass network structure, transmission, and refractive index are comprehensively characterized. Significantly, it is initially demonstrated that pure ZnS nanocrystals can be precipitated in GCs simply by a thermal treatment process. The composition and thermal treatment temperature dependencies of crystallization are studied using X‐ray diffraction spectroscopy, and the morphology of the nanocrystals by high‐resolution transmission electron microscope. The ChG GCs with embedded ZnS nanocrystals retaining good transparency can be a potential host laser material for divalent transition metals (e.g., Cr2+/Fe2+, etc.), and thus used for ultrabroadband tunable continuous or ultra‐short‐pulsed mid‐infrared fiber lasers.
