Design of Angular-offset Interstitial-Tube- Assisted Hollow-Core Fibers with Ultrahigh Mode Purity and Ultralow Loss
Hao Chen, Jiayi Chen, Dawei Ge +5
Antiresonant hollow-core fibres (AR-HCFs) have recently reached attenuation far below the Rayleigh-scattering limit of silica, but their inherently multimode nature remains a major…

Polarization-Differential Loss Enabled High Polarization Extinction in Hollow-Core Fibers
Yizhi Sun, Shoufei Gao, Xiangqi Wang +5
Delivering a well defined state of polarization over hollow core fibres (HCFs) is pivotal for next generation ultra stable photonic systems. Yet in all existing HCFs, whether biref…
