Near-Zero Modal-Dispersion (NEMO) Coupled-Core Multi-Core Fibers

نویسندگان

چکیده

Wepropose a design for coupled-core multi-core fibers that allows to achieve extremely low levels of modal dispersion. These fibers, which we dub NEar-zero MOdal-dispersion (NEMO) have an even number cores regularly distributed on circle, and the optimal parameters follow from simple condition independent cores. The modal-dispersion reduction trades off some fiber mode-mixing effectiveness, yet without compromising its beneficial property mitigating nonlinear signal distortions. semi-analytical tool developed this study effectively characterize effect various types perturbations ideal structure.

Systematic approach for designing zero-DGD coupled multi-core optical fibers.

An analytical method is presented for designing N-coupled multi-core fibers with zero differential group delay. This approach effectively reduces the problem to a system of N-1 algebraic equations involving the associated coupling coefficients and propagation constants, as obtained from coupled mode theory. Once the parameters of one of the cores are specified, the roots of the resulting N-1 eq...

Opto-mechanical inter-core cross-talk in multi-core fibers

Optical fibers containing multiple cores are widely regarded as the leading solution to the optical communications capacity crunch. The most prevalent paradigm for the design and employment of multi-core fibers relies on the suppression of direct coupling of optical power among cores. The cores, however, remain mechanically coupled. Intercore, opto-mechanical cross-talk, among cores that are ot...

Neural networks within multi-core optic fibers

Hardware implementation of artificial neural networks facilitates real-time parallel processing of massive data sets. Optical neural networks offer low-volume 3D connectivity together with large bandwidth and minimal heat production in contrast to electronic implementation. Here, we present a conceptual design for in-fiber optical neural networks. Neurons and synapses are realized as individual...

Modal content in hypocycloid Kagomé hollow core photonic crystal fibers.

The modal content of 7 and 19 cell Kagomé anti resonant hollow core fibers (K-ARF) with hypocycloid core surrounds is experimentally investigated through the spectral and spatial (S2) imaging technique. It is observed that the 7 and 19 cell K-ARF reported here, support 4 and 7 LP mode groups respectively, however the observation that K-ARF support few mode groups is likely to be ubiq...

Theoretical study on dispersion compensation in air-core Bragg fibers.

In a previous paper we developed a matrix theory that applies to any cylindrically symmetric fiber surrounded by Bragg cladding. Using this formalism, along with Finite Difference Time Domain (FDTD) simulations, we study the waveguide dispersion for the m = 1 mode in an air-core Bragg fiber and showed it is possible to achieve very large negative dispersion values (~ -20,000 ps/(nm.km)) with si...
