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 …

We simulate and analyze the mode properties and propagation effects of orbital angular
momentum (OAM) modes in a ring fiber. A ring fiber with 0.05 up-doping is designed in …

A new design of a circular photonic crystal fiber, which can support 26 OAM modes, is
proposed. The numerical analysis shows that the proposed fiber possesses very good …

In one embodiment, an optical fiber includes a first layer having a first refractive index and a
second layer surrounding the first layer, where the second layer has a second refractive …

A method of generating the first-order orbital angular momentum (OAM) modes in a single-
ring fiber is proposed and demonstrated through an all-fiber structure. The first-order OAM …

Due to the renewed demand on data bandwidth imposed by the upcoming capacity crunch,
optical communication (research and industry) community has oriented their effort to space …

Circular photonic crystal fibers (C-PCFs) have been proved to be a good candidate for
orbital angular momentum (OAM) modes supporting fiber, because they possess many …

Internet data traffic capacity is rapidly reaching limits imposed by nonlinear effects of single
mode fibers currently used in optical communications. Having almost exhausted available …

摘要根据轨道角动量(OAM) 密度的定义, 推导出高阶贝塞尔光束和高阶拉盖尔高斯光束一样具有
轨道角动量, 且不存在发散角的问题, 并基于该理论提出了一种适合基于高阶贝塞尔函数的OAM …

Optical vortices, which carry orbital angular momentum, form infinite-dimensional basis sets
of orthogonal states, which make them attractive for mode-division multiplexing systems. We …
