Angular momentum, a fundamental physical quantity, can be divided into spin angular
momentum (SAM) and orbital angular momentum (OAM) in electromagnetic waves. Helically …

Solitons are waveforms that preserve their shape while propagating, as a result of a balance
of dispersion and nonlinearity,. Soliton-based data transmission schemes were investigated …

An optical vortex having an isolated point singularity is associated with the spatial structure
of light waves. A polarization vortex (vector beam) with a polarization singularity has …

We use a wideband optical comb source with 10THz bandwidth for 2.15 Pb/s transmission
over 31km of a new, homogeneous 22-core single-mode multi-core fiber using 399× 25GHz …

Forthcoming capacity scaling requirements of optical networks and advances in optical fiber
communications beyond the omnipresent single-mode fiber operating over the conventional …

The potential transmission capacity of a standard single-mode fiber peaks at around
100Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last …

Space division multiplexing (SDM) is mainly seen as a means to increase data throughput
and handle exponential traffic growth in future optical networks. But its role is certainly more …

This study presents an evaluation of the time and modulation frequency-varying power
transfer of crosstalk in a homogeneous multi-core fiber (MCF). Experimental observations …

We discuss optical transmission using homogeneous, single-mode, multicore fibers. We first
describe the key fiber properties that can affect transmission, such as intercore crosstalk and …

We investigate the impact of intercore crosstalk on the achievable transmission distance of
three square quadrature amplitude modulation (QAM) formats. We show that increasing …
