In the last three decades, light's orbital angular momentum (OAM) has been of great interest
because it has unique characteristics that make it sought after in many research fields …

As we celebrate 30 years since light's orbital angular momentum (OAM) was connected to its
spatial structure, we reflect on the advances made in fundamental science and applications …

The review describes general principles and characteristics of inhomogeneously polarized
paraxial optical fields and, especially, the polarization singularities (PSs). Main parameters …

We propose a method for the selective generation of high-order orbital angular momentum
(OAM) modes by twisting a ring-core fiber (RCF). Theoretically, 22 OAM modes can be …

Encoding information using OAM beams as carriers greatly alleviates the capacity crisis in
communication systems. When transmitted through the atmospheric channel, OAM beams …

We design a graded-index ring-core fiber with a GeO2-doped silica ring core and SiO2
cladding. This fiber structure can inhibit the effect of spin-orbit coupling to mitigate the power …

We propose a high-security hyperchaotic orthogonal frequency division multiplexing
(OFDM) encryption scheme based on the orbital angular momentum system, and our …

We theoretically and experimentally proposed the generation method of third-order orbital
angular momentum (OAM) modes with reduced losses by cascading two adiabatic mode …

A novel twisted ring core fiber incorporating chiral material into the ring core is proposed,
which supports orbital angular momentum (OAM) modes. Results show that between …

Orbital angular momentum (OAM) mode sorter is crucial for various OAM (de) multiplexing
applications. However, it is challenging to sort the OAM mode without destroying its helical …
