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…

Four-fold truncated double-nested anti-resonant hollow-core fibers with ultralow loss and ultrahigh mode purity

Shoufei Gao, Hao Chen, Yizhi Sun +5

Hollow-core fibers are inherently multimode, making it crucial to filter out higher-order modes within the shortest possible fiber length for applications such as high speed cohere…
