Ultra‐Low Loss Weakly Coupled Few‐Mode Hollow‐Core Anti‐Resonant Fiber Enabling Eight Channels via Differential Wall Thickness and Truncated Tubes

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
A novel ultra‐low loss, weakly coupled few‐mode hollow‐core anti‐resonant fiber is realized through truncated tubes and differential wall thickness, which can support eight spatial modes as independent channels. The effective refractive index difference between adjacent modes is greater than 1.0 × 10−4, and the intrinsic loss of all target modes at ...
