Hollow-core anti-resonant fibers (HC-ANF) have the advantages of low scattering loss, wide bandwidth and simplicity of preparation, but are sensitive to bend, which limits their practical applications. On the contrary, hollow-core photonic bandgap (H

In this work, we design and numerically investigate a silica-cladded Germania-doped ring-core fiber (RCF) that supports orbital angular momentum (OAM) modes with all-normal dispersion. By optimizing the structure parameters of the designed RCF, an al

The abrupt termination of periodic structures in hollow-core photonic bandgap fiber (HC-PBF) cladding introduces surface modes (SMs). This results in a high loss and small available bandwidth. This has become an important factor that restricts the de

Chalcogenide glass (ChG) has been fabricated into on-chip integrated waveguides owing to its high nonlinear refractive index. However, the systematic research of Ge-Sb-S glass shows that Ge25Sb10S65 glass has greater hardness and stronger resistance
