Cylindrical vector beams and vortex beams, two types of typical singular optical beams
characterized by axially symmetric polarization and helical phase front, possess the unique …

Optical orbital angular momentum (OAM) has become a hot research topic because of its
unique properties due to its spiral distribution of phases. The production and transmission of …

Based on the Richards-Wolf formalism, we obtain for the first time a set of explicit analytical
expressions that completely describe a light field with a double higher-order singularity …

We show that if a nonzero E-field intensity is found in the focus of a circularly polarized
optical vortex with phase singularity or a higher-order azimuthally polarized beam with …

In this paper, the tight focusing of high-order cylindrical vector beams (beams with
polarization singularity) was investigated. Using the Richards-Wolf formalism, there were …

In optical fiber, the Orbital Angular Momentum (OAM) mode is a special mode with spatially
infinite orthogonality. It provides a new multiplexing method to the communication capacity …

Featured Application In this paper, the basic concepts of fiber modes, the principle of
generation and detection of orbital angular momentum (OAM) modes are exhaustive …

As two groups of bases in fibers, cylindrical vector (CV) modes and the orbital angular
momentum (OAM) modes can be transformed into each other. Several transformation …

Photonic spatial quantum states are a subject of great interest for applications in quantum
communication. One important challenge has been how to dynamically generate these …
