“…In the literature, these surface defects in fluoride glasses are commonly attributed to crystallisation during the preform and fibre fabrication processes. [6][7][8][9] Here we show that a compositional change at the surface of the glass during preform fabrication is also a contributing factor to the poor surface quality observed on optical fibres fabricated from fluoride glasses.…”

“…This has been shown previously to cause fragility and high loss in fluoride and fluoroindate optical fibres. 8,16 Treated preforms which no longer have this surface layer show reduced corrugations on the neck-down region. Fibre loss and strength are both improved, which is attributed to a lower concentration of surface defects for the fibres.…”

May 2017Surface analysis and treatment of extruded fluoride phosphate glass preforms for optical fibre fabrication Abstract Fabrication of fluoride phosphate glass optical fibres using the extrusion method for preform fabrication has been studied using the commercial Schott N-FK51A glass. The extrusion step was found to create a surface layer of differing composition from the bulk glass material, leading to defects drawn down onto the optical fibre surface during fibre fabrication, resulting in high loss and fragile fibres. Similar phenomena have also been observed in other fluoride-based glasses. Removal of this surface layer from preforms prior to fibre drawing was shown to improve optical fibre loss from >5 dB/m to 0.5 -1.0 dB/m. The removal of this surface layer is therefore necessary to produce low-loss fluoride phosphate optical fibres.

“…Another unique property of fluoride glasses is their extremely broad transmission window from the UV (∼300 nm) to the MIR (4-6 μm for ∼1-m-long fiber) [64,167,201,202]; see Fig. 10.…”

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR spectrum, which is becoming increasingly more prominent in a variety of scientific disciplines and technological applications. Despite well-established efforts on the fabrication of IR fibers in past decades, a number of remarkable breakthroughs have recently rejuvenated the field-just as related areas in IR optical technology are reaching maturation. In this review, we describe both the history and recent developments in the design and fabrication of IR fibers, including IR glass and single-crystal fibers, multimaterial fibers, and fibers that exploit the transparency window of traditional crystalline semiconductors. This interdisciplinary review will be of interest to researchers in optics and photonics, materials science, and electrical engineering.

“…Preliminary evaluation of fiber strength via a measurement of the bend radius (the radius at which the fiber breaks [49]) has yielded values of 21.5 ± 8.7 mm and 16.3 ± 5.9 mm for the TZNL and GPL5 bare fibers, respectively. The smaller bend radius for the germanate fiber indicates higher fiber strength.…”
