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.

Silicon photonics for space-division multiplexing

2012 IEEE Photonics Society Summer Topical Meeting Series, 2012
An allure of space-division multiplexing is a very high optical connection density yet it may require significant MIMO processing. Silicon photonics is well suited for handling both.
