Anti-Resonant Hollow Core Fibers
Photonic Crystal & Multicore Fibers
Overview
Optical signal in a hollow core anti-resonant fiber propagates in an air core surrounded by single ring of anti-resonant tube elements. Guidance is based on an anti-resonance from the thin glass membranes constituted by the non-touching tubes surrounding the hollow core. The extremely low overlap of guided power with the surrounding silica, less than 2×10-5, added to the mode effective area, confers to this fibre design record material non-linearity.

Dissolved gas sensing using an anti-resonant hollow core optical fiber
Applied Optics Vol. 60, Issue 33, pp. 10354-10358 (2021)
https://doi.org/10.1364/AO.439787The sensor used consists of a 1650.9 nm distributed feedback laser (DFB) (15 mW LD-PD/Ideal Photonics) coupled to a 5 m AR-HCF (Exail IXF-ARF-45-240) using an FC/APC connector for the laser fiber and an FC/PC connector for the AR-HCF.

26th Optoelectronics and Communications Conference OSA Technical Digest (Optica Publishing Group, 2021), paper S4E.3
https://opg.optica.org/abstract.cfm?URI=OECC-2021-S4E.3For this study, we used Exail IXF-ARF-45-240, an HCF with an anti-resonant structure that is commercially available. We investigated the relationship between misalignment and coupling loss when connecting this fiber with a butt joint.
