“…In the past decade broadband-guiding hollow-core fibers based on anti-resonant (AR) and inhibiting-coupling guiding mechanism, have become extremely popular (see recent reviews [1][2][3]). These fibers support extremely large transmission bandwidths, making them excellent waveguides for studying ultrafast nonlinear optics in gases [4].…”

Poor-man’s model of hollow-core anti-resonant fibers

et al. 2018

We investigate various methods for extending the simple analytical capillary model to describe the dispersion and loss of anti-resonant hollow-core fibers without the need of detailed finite-element simulations across the desired wavelength range. This poor-man's model can with a single fitting parameter quite accurately mimic dispersion and loss resonances and anti-resonances from full finite-element simulations. Due to the analytical basis of the model it is easy to explore variations in core size and cladding wall thickness, and should therefore provide a valuable tool for numerical simulations of the ultrafast nonlinear dynamics of gas-filled hollow-core fibers.

“…For our experiment we choose to use Xenon due to its high nonlinearity [26] and the very low reactivity. There are several geometries of hollow-core fibers, the one that we consider in this paper is known as single-ring fiber [27,28]. It consists of a ring of capillaries attached to the inner surface of a glass tube, see Fig.…”

Progress toward third-order parametric down-conversion in optical fibers

et al. 2020

View full text Add to dashboard Cite

Optical fibers have been considered an optimal platform for third-order parametric downconversion since they can potentially overcome the weak third-order nonlinearity by their long interaction length. Here we present, in the first part, a theoretical derivation for the conversion rate both in the case of spontaneous generation and in the presence of a seed beam. Then we review three types of optical fibers and we examine their properties in terms of conversion efficiency and practical feasibility.

“…On the other hand, different materials can be co-extruded to make core and cladding layers simultaneously [72]. Recently, the anti-resonant MOF has been widely investigated because of its superior performance in light delivery [73]. When the stacking method is used, the structure is very limited; for example, it is difficult to obtain good negative curvature structure with more inner rings [74].…”

Multifunctional Smart Optical Fibers: Materials, Fabrication, and Sensing Applications

et al. 2019

View full text Add to dashboard Cite

This paper presents a review of the development of optical fibers made of multiple materials, particularly including silica glass, soft glass, polymers, hydrogels, biomaterials, Polydimethylsiloxane (PDMS), and Polyperfluoro-Butenylvinyleth (CYTOP). The properties of the materials are discussed according to their various applications. Typical fabrication techniques for specialty optical fibers based on these materials are introduced, which are mainly focused on extrusion, drilling, and stacking methods depending on the materials' thermal properties. Microstructures render multiple functions of optical fibers and bring more flexibility in fiber design and device fabrication. In particular, micro-structured optical fibers made from different types of materials are reviewed. The sensing capability of optical fibers enables smart monitoring. Widely used techniques to develop fiber sensors, i.e., fiber Bragg grating and interferometry, are discussed in terms of sensing principles and fabrication methods. Lastly, sensing applications in oil/gas, optofluidics, and particularly healthcare monitoring using specialty optical fibers are demonstrated. In comparison with conventional silica-glass single-mode fiber, state-of-the-art specialty optical fibers provide promising prospects in sensing applications due to flexible choices in materials and microstructures.
