Singularities splitting phenomenon for the superposition of hybrid orders structured lights and the corresponding interference discrimination method

Nanophotonics, 2022
It is the basic characteristic of pure vortex light that there is a phase singularity at the origin. Such a singularity may be multiple degenerate, which determines the order of vortex light. Singularities splitting phenomenon means that singularities no

Accurate Control of Surface Modes in a Hollow-Core Photonic Bandgap Fiber

IEEE Photonics Journal, 2022
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.
