“…This fabrication approach can be advantageous when special glass compositions are desired. [60][61][62] Furthermore, it can be utilized in combination with, for example, MCVD to increase fiber yield by embedding the MCVD-fabricated assembly into another tube. This approach shortens the production cycle and also enables the use of significantly cheaper, lower-quality glass for the outer layers of the cladding.…”

As demand for customized specialty fibers grows, standardized production methods face challenges. This article reviews industry standards and discusses potentially disruptive techniques that enable rapid prototyping and fabrication of optical fiber devices. Furthermore, we showcase laser powder deposition's (LPD) potential for additive manufacturing (AM) of customized glass structures. In the case of, for example, fiber preforms, although the feasible size is smaller than the industry standard, utilizing laser‐based manufacturing techniques for a small batch production presents an attractive avenue for rapid prototyping and expedites material and design optimization. In the realm of AM of glass, LPD offers numerous benefits, including minimal shrinkage, high densification, and the ability to tailor glass composition to achieve desired optical properties. The article reviews the latest achievements and highlights future directions in this technology.

“…This approach's potential advantage is obtaining optical ber sources with e cient emission by exploiting the properties of the active crystals, i.e., an ordered lanthanide environment with controlled phonon energy and RE concentration. Currently, there are two main ways to obtain a ber with a crystalline phase by in-situ processes of controlled crystallisation: i) annealing of the ber after fabrication [3] and ii) ex-situ by introducing crystals into the glass prior to the ber fabrication by different methods [4,5,6,7] or a crystallisation phenomenon during the ber drawing [8,9]. Several ber constructions with oxide and uoride nano-and micro-crystals doped with Nd, Er, and Tm ions have been presented by controlled crystallisation, where an essential aspect was to determine the RE ion environment con rmed by structural studies leading to the increase of luminescence properties (e.g., intensity and lifetime).…”

Optical fiber with YPO4:Pr3+ nanocrystals (NCs) is presented for the first time using the glass powder - NCs doping method. The method’s advantage is separate preparation of NCs and glass to preserve luminescent and optical properties of NCs once they are incorporated into optical fiber. The YPO4:Pr3+ nanocrystals were synthesized by the solvothermal method, optimized for size (<100 nm), shape, Pr3+ ions concentration (0.2 mol%), and emission lifetime. The core glass was selected from the non-silica P2O5-containing system with refractive index (n = 1.788) close to the NCs (no=1.657, ne=1.838). Optical fiber was drawn by modified powder-in-tube method prior pre-sintering of glass powder - YPO4:Pr3+ (wt. 3%) mixture to form optical fiber preform. Luminescent properties of YPO4:Pr3+ and optical fiber showed their excellent agreement, including sharp Pr3+ emission at 600 nm (1D2-3H4) and 1D2 level lifetime (τ = 156±5 µs) under 488 nm excitation. The distribution of the YPO4:Pr3+ NCs in optical fiber were analyzed by TEM-EDS in the core region (FIB-SEM-prepared). The successful usage of glass powder - NCs doping method was discussed in the aspect of promising properties of the first YPO4:Pr3+ doped optical fiber as a new way to develop active materials for lasing applications, among others.
