“…Previous work by our group [4][5][6][7] showed that it is possible to draw superconductive YBCO, bismuth-strontium-calcium copper oxide and tin powders as well as a lead wire into glass fibres using a glass working lathe. These studies proved the possibility of manufacturing glass fibres with a superconductive core.…”

“…However, the drawn fibre lengths were restricted to a short scale due to the limited working distance of the glass working lathe as detailed in ref. [4]. Therefore, due to the lack of scalability, fibre manufacturing using the glass working lathe can only be used as a preliminary method of assessing the feasibility of the proposed drawing process.…”

This work introduces the first reported experiments on drawing YBa 2 Cu 3 O 7−x (YBCO) into fibres with a fused silica cladding using a fibre draw tower to manufacture YBCO glass fibres. These fibre draw experiments allowed manufacturing fibre sections with core diameters between 50 and 200 μm and a length of around 1.2 m. However, reactions between the fused silica cladding and the YBCO core were revealed by the fibre drawing process. Therefore, this study focusses on investigating these reactions (in as-drawn fibres as well as after additional heat-treatments) using energy dispersive spectroscopy analyses on an environmental scanning electron microscope as well as using X-ray photoelectron spectroscopy analyses and a cross-polarized light study. The results showed the formation of silica precipitations inside the as-drawn YBCO core, forming an interface layer between the core and the cladding regions, as well as the presence of a high silicon content inside the core with a possible silicate formation. Additional heat-treatments have shown the formation of silica and copper oxide co-precipitations at 900 • C. In addition, heat-treatments at higher temperatures have shown the occurrence of further reactions, which led to a degradation of the core and the formation of new phases. Keywords. YBa 2 Cu 3 O 7−x ; YBCO core glass fibres; YBCO-silica reaction phases; superconductor wires.

The field of hybrid optical fibers is one of the most active research areas in current fiber optics and has the vision of integrating sophisticated materials inside fibers, which are not traditionally used in fiber optics. Novel in‐fiber devices with unique properties have been developed, opening up new directions for fiber optics in fields of critical interest in modern research, such as biophotonics, environmental science, optoelectronics, metamaterials, remote sensing, medicine, or quantum optics. Here the recent progress in the field of hybrid optical fibers is reviewed from an application perspective, focusing on fiber‐integrated devices enabled by including novel materials inside polymer and glass fibers. The topics discussed range from nanowire‐based plasmonics and hyperlenses, to integrated semiconductor devices such as optoelectronic detectors, and intense light generation unlocked by highly nonlinear hybrid waveguides.
