We propose and design a hollow As2S3 ring-core photonic crystal fiber (PCF) with 514 radially fundamental orbital angular momentum (OAM) modes over 360 nm communications bandwidth across all the O, E, S, C, and L bands. The designed PCF with 40 \mu \text{m}-radius air core and 150 nm-width As2S3 ring can support eigenmodes up to HE130,1 and EH128,1. The numerical analysis shows that the designed ring PCF has large effective refractive index contrast, and can transmit up to 874 OAM modes near ...

Beams carrying orbital-angular-momentum (OAM) have gained much interest due to their unique amplitude and phase structures. In terms of communication systems, each of the multiple independent data-carrying beams can have a different OAM value and be orthogonal to all other beams. This paper will describe the use of multiplexing and the simultaneous transmission of multiple OAM beams for enhancing the capacity of communication systems. We will highlight the key advances and technical challenges i...

Abstract null null null null null null null There has been a growing interest in orbital angular momentum (OAM) multiplexed communication links because of their potential for high capacity data transmission. However, OAM multiplexed communication links are sensitive to various degradation effects, and one of the key challenges is to compensate for the potential intermodal crosstalk. In this chapter, we review the causes and mitigation techniques for channel crosstalk in OAM multiplexed communica...

In this work, we propose and design a highly dispersive coupled ring-core fiber (CRF) with two concentric high-index rings using Schott glass for orbital angular momentum (OAM) modes. By properly selecting the fiber geometrical parameters, the OAM130,1 mode supported in the proposed CRF has a large negative chromatic dispersion (CD) of −20 271 ps/(nm km) at 1260.4 nm. We also show that the proposed CRF could be an excellent candidate for various CD-related applications of OAM modes in the optica...

A pivotal issue of the conventional optical fiber communications networks is to meet the explosively increasing requirement in data traffic. In order to meet this ever-increasing demand, there have been a lot of research and industrial development efforts to utilize the photon in various dimensions such as wavelength division multiplexing (WDM), space division multiplexing (SDM), mode division multiplexing (MDM) and so on. Fueled by emerging bandwidth-hungry applications, orbital angular momentu...

Light-carrying orbital angular momentum (OAM) has recently drawn extensive attention from researchers due to its unique field distribution. As a result of the intrinsic orthogonality among OAM modes with different topological charge values, they can be used as a modal basis in the mode-division multiplexing (MDM) optical communications systems. For fiber-based optical systems, chromatic dispersion induces temporal optical pulse broadening, which seriously limits the rate of information transmiss...

We design and simulate an all-normal dispersion arsenic trisulfide (As 2 S 3 ) photonic crystal fiber (PCF) with high nonlinearity to enable a flat and coherent orbital angular momentum (OAM) supercontinuum (SC) generation. The photonic crystal fiber features a near-zero and flat negative dispersion with variation between -96.5 and -36.5 ps/(nm·km) over a 940-nm wavelength range from 1740 to 2680 nm. A 1946-nm supercontinuum forms from 959 to 2905 nm at -20 dB level which covers a 1.6-octave ban...
