“…As shown in Fig. 5d, the bandwidth of the transmission window in the HC-BARF is up to 800 nm, which is larger than that reported in previous literature [20,23],670nm bandwidth is obtained in literature [23], and it can cover the entire O+S+C+L communication band (1.28-1.6 μm), which is basically consistent with that reported in the literature [24,25],And our loss at is much lower than that reported in the literature [24]. Moreover, it is difficult to obtain long-distance long fiber in the laboratory for the complex structure of fiber reported in the literature [24].…”

A novel hollow-core antiresonant fiber with a Bragg structure is proposed. It is numerically simulated using a commercial finite element method, and optical properties of the fiber, such as mode field, confinement loss, and bend loss, are numerically analyzed. The proposed hollow-core antiresonant fiber has advantageous optical properties, such as ultralow confinement loss, large bandwidth, and low bend loss. The structural advantage of the hollow-core Bragg antiresonant fiber also facilitates the fabrication of long-distance hollow-core antiresonant fibers. Additionally, this fiber offers potential applications in long-distance communications, data transmission, and laser power delivery.

“…Moreover, it is difficult to obtain long-distance long fiber in the laboratory for the complex structure of fiber reported in the literature [24]. In addition, the surface scattering loss (SSL) is calculated [23] because it is significant issue for hollow core fiber as shown in Fig. 5(d).…”

“…Noteworthy, out of all numerically designed fiber geometries with significantly low loss in near infrared domain, few designs need special mention. One such host is a NARF with nested double cladding rings [37] which exhibit losses of 1 × 10 −3 dB km −1 at 1400 nm, NARFs with connecting circle or, elliptical nesting circular tube also predict 0.7 × 10 −3 -3.694 × 10 −3 dB km −1 at 1.06 µm [38,39]. However, these designs introduce additional AR membranes which could pose a fabrication challenge.…”

We report an optimized design of six-ring nodeless antiresonant fiber (NARF) in both single and nested ring configurations in the visible wavelength regime. Proposed fibers exhibit a record low loss of 6.7 × 10^(−4) dB/km at 630 nm with less than 1 dB/km over a broad 330 nm bandwidth, achieved by the incorporation and optimization of nested elements in the primary cladding tubes. A comprehensive analysis, utilizing finite difference algorithm, to study the role of structural parameters of the hollow core fiber viz. tube thickness and gaps between the tubes on the loss spectrum is also presented. A comparative analysis of NARF designs using tube thickness in different anti-resonant bands is also included. The bend robustness, polarization analysis, dispersion, and fabrication tolerances are investigated. Proposed low-loss fibers in the visible wavelength regime can drastically bring down the cost and complexity of quantum communication systems.

“…Two distinct types of HCFs based onlight guiding mechanism are photonic bandgap hollow core ber (PBG-HCF) and anti-resonant hollow core ber (HC-ARF) [13].The PBG-HCF, which offers low loss with a constrained transmission bandwidth and severe group velocity dispersion, uses the photonic bandgap effect to direct light [14][15][16]. A 19-cell HC-PBGF with 4.9 dB/km loss and ~ 3×10 − 4 birefringence was reported by Fini et al [15], however it had a restricted bandwidth of 10 nm.In contrast to HC-PBGFs, HC-ARFs display outstanding optical properties, such as broad transmission bandwidth, improved group velocity dispersion [17], and very low loss [18], etc. by preventing the coupling between the core and cladding modes [19].…”

In this paper, a single ring hollow-core anti-resonant fiber (HC-ARF) with five elliptical nested tubes and a silicon layer is presented and investigated. The geometrically optimized HC-ARF, proposed here, exhibits highest birefringence of 2.95×10− 4 at 1550 nm by maintaining a birefringence level of > 10− 4 for a bandwidth of 58 nm. The confinement loss of this fiber reaches to a very low value of 7.57×10− 3 dB/m at 1550 nm and sustains a loss of < 0.75 dB/m within the highly birefringent region. A higher order mode extinction ratio of 51, for our fiber, ensures a singlemode operation at 1550 nm.Moreover, the HC-ARF offers low bend loss of 0.08 dB/m at 2 cm of bend radius and the bend loss remains < 0.08 dB/m from 3 cm of bend radius to onwards.
