With growing interest in the spatial dimension of light, multimode fibers, which support
eigenmodes with unique spatial and polarization attributes, have experienced resurgent …

Coherent vortex structures are fascinating physical objects that are widespread in nature:
from large scale atmospheric phenomena, such as tornadoes and the Great Red Spot of …

Propagation-invariant or nondiffracting optical beams have received considerable attention
during the last two decades. However, the pulsed nature of light waves and the structured …

Light that can carry orbital angular momentum (OAM) has found a variety of applications in
super-resolution microscopy, optical communications, and laser machining, bringing up the …

Herein, the generation of an optical vortex array dubbed the flower‐shaped optical vortex
array (FOVA) is proposed and experimentally demonstrated using a single optical path …

We study the generation of spin-orbit (SO) modes via four-wave mixing (FWM)-based
parametric amplification. SO modes carry quantized total angular momentum (TAM), and we …

In this study, an anomalous ring-connected optical vortex array (ARC-OVA) via the
superposition of two grafted optical vortices (GOVs) with different topological charges (TCs) …

We present a quantum-mechanical model that describes fiber-based frequency conversion
by four-wave-mixing Bragg scattering in the presence of Raman interactions. In the case of …

Stimulated Raman scattering is a particularly robust nonlinearity, occurring in virtually every
material because its spectral linewidth and associated frequency shift do not typically …

Orbital angular momentum (OAM) modes over photonic crystal fibers (PCFs) have shown
great capability in unleashing the available data rates in optical communication systems. In …
