“…With the adoption of our model, we hope more complicated phenomenon about ARFs can be explained. In many recent designs, more inter-medium interfaces and irregular glass wall shapes have been introduced for achieving a lower loss level, such as the nested structure in [20,51] and the elliptical tube structure in [52,53]. …”

Abstract:Simple structures are always a pursuit but sometimes not easily attainable. It took researchers nearly two decades for conceiving the structure of single-ring hollow-core negative curvature fiber (NCF). Recently NCF eventually approaches to the centre of intense study in fiber optics. The reason behind this slow-pace development is, undoubtfully, its inexplicit guidance mechanism. This paper aims at gaining a clear physical insight into the optical guidance mechanism in NCF. To clarify the origins of light confinement, we boldly disassemble the NCF structure into several layers and develop a multi-layered model. Four physical origins, namely single-path Fresnel transmission through cascaded interfaces, near-grazing incidence, multi-path interference caused by Fresnel reflection, and glass wall shape are revealed and their individual contributions are quantified for the first time. Such an elegant model could not only elucidate the optical guidance in existing types of hollow-core fibers but also assist in design of novel structure for new functions.

“…In turn, the resonant contributions to the mode dispersion are also accurately obtained. What remains to obtain the total loss of the HC-AR fiber is a single fitting parameter, expressing the deviation from a thin dielectric capillary to the more advanced HC-AR fiber designs emerging recently [12][13][14][15][16][17][18].…”

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.

“…In this paper we demonstrate via finite element modeling using COMSOL Multiphysics® software that the optical loss of different types of negative curvature fibers can decrease significantly by replacing the circular capillary tubes with elliptical ones. It has been proposed recently that this design can decrease the loss of these fibers at a wavelength of 1.06 µm [21,22]. In this paper we present a comprehensive analysis of designing low loss negative curvature fibers with elliptical tubes at the telecommunication wavelength of 1.55 µm.…”

 Abstract -Regular and nested negative curvature optical fibers with elliptical capillary tubes have been proposed in this paper for ultra-low loss guidance at the telecommunication wavelength. Finite element modeling shows that these fibers can have lower loss compared to their counterparts with circular tubes. These hollow core fibers with low loss and large bandwidth can have huge potential applications in data transmission, sensing, high power delivery and serve as an ideal platform for the study of a wide variety of nonlinear optical effects.
