High-Polarization-Extinction Raman Conversion in Gas-Filled Polarization-Maintaining Hollow-Core Fibers
Xianhao Qi, Pau Arcos, Yizhi Sun +4
Gas-filled hollow-core fibers (HCFs) have emerged as a versatile platform for high-power nonlinear optics, enabling phenomena from ultrafast pulse compression to broadband frequenc…

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…
