Mode and Polarization Division Multiplexing Based on Chalcogenide‐Glass‐on‐Thin‐Film Lithium Niobate [PDF]

Nanophotonics
High‐index GeSbSe chalcogenide glass loaded on thin‐film lithium niobate enables compact broadband mode‐ and polarization‐division multiplexing. Exploiting direction‐dependent birefringence of x‐cut LNOI, a four‐channel mode (de)multiplexer and asymmetric directional coupler‐based polarization splitter–rotator are demonstrated with great performance in

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

Nanophotonics
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 ...
