Abstract

Hollow-core core fibers with an anti-resonant nodeless structure are showing an incredible ability for mode confinement within the realm of optical transport. A subset of this application, high-energy laser beam delivery, requires extremely finite tolerances and precise design constraints in what are the traditional solid-core fiber solutions whereas nested antiresonant hollow-core fibers (NANF) allow for significantly more flexibility in both design and application. Increasing the number of capillaries in a NANF increases the number of allowed optical modes to propagate through the fiber thus reaching the few-mode and multi-mode regime, however increasing the modal count in propagation is not always desired. This study presents a comparison between experimental and simulated performance in the kW regime of a NANF with an internal structure consisting of five nested capillaries.
