Degree of Coherence in Space-Division Multiplexed Transmission

Journal of Lightwave Technology, 2014
We generalize the concept of degree of polarization of single-mode fields to multi-mode fields by introducing a new parameter that we define degree of mutual coherence. The new definition enables characterizing by a single parameter the quality of the signal corrupted by various linear and nonlinear impairments at the output of an optical transmission ...

Modeling of Nonlinear Distortion in Space-Division Multiplexing

2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023
We review the main models of space-division multiplexing transmissions in fiber optics working in the nonlinear regime, including perturbative modeling, the ergodic Gaussian noise model, and their implications on system analysis.

Space division multiplexing holography

Proceedings of the IEEE, 1969
A technique is proposed for multiple information storage in a sampled hologram in long-wavelength holographies. An experiment on the proposed technique is conducted to construct a hologram using 15 kHz sound waves and to reconstruct images using laser light.

Optical technologies for space division multiplexing

2014 13th Workshop on Information Optics (WIO), 2014
Many technological challenges have to be overcome before a cost and energy efficient fiber communication system based on space division multiplexing (SDM) can be realized. In this paper we review recent R&D efforts in developing optical components for SDM networks.

Photonic lantern spatial multiplexers in space-division multiplexing

2013 IEEE Photonics Society Summer Topical Meeting Series, 2013
Photonic-lanterns are lossless spatial-multiplexers that scramble N signals onto the N modes of a multi-mode fiber without mode- dependent loss. They can scale to large N and have enabled transmission over a fiber supporting 12 spatial and polarization-modes.

Space-Division Multiplexing for PON Applications

Advanced Photonics 2016 (IPR, NOMA, Sensors, Networks, SPPCom, SOF), 2016
The spatial degrees of freedom afforded in few-mode and/or multi-core fibers can potentially be utilized to improve the performance of passive-optical networks. Optical and signal-processing techniques for managing crosstalk for PON in a cost-effective manner are presented.

Next-generation fibers for space-division-multiplexed transmissions

2014 The European Conference on Optical Communication (ECOC), 2014
This paper reviews the most recent advances on next-generation fibers for space-division-multiplexed transmissions. These fibers can be classified into different categories, depending on the way the inherent crosstalk issue is addressed, and have thus different characteristics and limitations.
