We present an optical fiber supporting 36 information bearing orbital angular momentum
(OAM) states spanning 9 OAM orders. We introduce design techniques to maximize the …

We demonstrate a 2-channel orbital angular momentum (OAM) multiplexed free space
optical communication (FSO) link using perfect optical vortex (POV) beams. POV beams are …

Light carries both orbital angular momentum (OAM) and spin angular momentum (SAM),
related to wavefront rotation and polarization, respectively. These are usually approximately …

We experimentally demonstrate a free-space optical communication link using perfect vortex
beams. Perfect vortex beams with different topological charges are generated using a phase …

Enabled by an enhanced effective index separation (Δneff= 1.7× 10^− 4) and low
transmission loss (0.8 dB/km), OAM states are propagated over 13.4 km in an air core fiber …

Orbital angular momentum (OAM) of light is a promising means for exploiting the spatial
dimension of light to increase the capacity of optical fiber links. We summarize how OAM …

Optical fibers are widely used for long links (intercontinental, terrestrial optical backbone)
and short scopes (data center, access network). Certain fibers, called optical fibers specialty …

In this paper, a novel dual-guided microstructured fiber supporting orbital angular
momentum (OAM) mode and linear polarization (LP) mode transmission is proposed to …

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 …

The spin–orbit coupling of light propagating in optical fiber can be dramatically enhanced by
the presence of a high-contrast interface in the refractive index profile, even for modes that …
