50 μm Multimode Fibers for Mode Division Multiplexing

Journal of Lightwave Technology, 2016
50-μm-diameter graded-index core multimode fibers can be adapted to mode-division-multiplexed transmissions that use multiple-input-multiple-output digital signal processing and selective mode multiplexing. We realize and characterize such fibers and compare them to low-differential-mode-group-delay few-mode fibers.

Multimode Fibers for Mode Division Multiplexing

Conference on Lasers and Electro-Optics, 2017
Graded-index-core multimode fibers can be appropriately rescaled in diameters and optimized to have low differential mode group delays for 6 to 36 spatial modes for multiple-input-multiple-output mode-division-multiplexed transmissions.

Bidirectional mode-division multiplexers with antireflection gratings

Applied Optics, 2018
A bidirectional mode-division multiplexer (BMDM) with antireflection gratings is designed, and its performance in terms of S-parameters is presented. A BMDM can (de)multiplex three modes with only two waveguides and a Bragg grating. The impact of return losses on the performance of BMDMs is studied and antireflection gratings are designed to reduce ...

High-Capacity Mode Division Multiplexing Transmission Technology

Optical Fiber Communication Conference (OFC) 2022, 2022
Mode division multiplexing is an attractive method of increasing the transmission capacity. This paper presents the 402.7-Tbit/s weakly coupled 10-mode-multiplexed transmission over 48 km and 50.47-Tbit/s standard cladding coupled 4-core fiber transmission over 9,150 km.

On-Chip Mode-division Multiplexing with Modal Crosstalk Mitigation

Optical Fiber Communication Conference (OFC) 2020, 2020
We experimentally demonstrate modal crosstalk mitigation over an on-chip mode-division multiplexing link employing low-coherence matched detection. 20-Gbaud QPSK and 8-PSK mode-multiplexed signals are successfully transmitted with a maximum modal crosstalk of −6.5 dB.

On-chip mode division multiplexing technologies

SPIE Proceedings, 2016
Space division multiplexing (SDM) is currently widely investigated in order to provide enhanced capacity thanks to the utilization of space as a new degree of multiplexing freedom in both optical fiber communication and on-chip interconnects. Basic components allowing the processing of spatial modes are critical for SDM applications.

First Demonstration of Polarization-Multiplexing Combined with On-Chip Mode-Division-Multiplexing

Optical Fiber Communication Conference, 2014
Polarization-multiplexed data is transmitted jointly with on-chip 2-mode mode-division-multiplexed data. Error-free operation and 5 dB of power penalty at an aggregate 40-Gb/s data rate are demonstrated, showing potential for pol-mux and mode-division-multiplexing networks on chip.

Design of Hollow Optical Fiber for Mode Division Multiplexing

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
A study is presented of the hollow optical fiber (HOF) properties needed to achieve 10-mode multiplexing transmission. A combination of mode division multiplexing (MDM) processing with optical LP mode separation is proposed to prevent the need for MDM computation. The impact of modal properties as chromatic dispersion and the differential mode delay of

Optical Amplifiers for Mode Division Multiplexing

2018
Space division multiplexing (SDM) has attracted considerable attention from the optical fiber communication community as a promising means to increase the transmission capacity per fiber and, more importantly, to reduce the associated cost per transmitted information bit by utilizing multiple spatial channels within a single strand of glass.

Adaptive MIMO Signal Processing for Mode-division Multiplexing

Optical Fiber Communication Conference, 2012
The fiber-optic multiple-input multiple-output (MIMO) channel is analyzed. For a 6×6 MIMO experiment over 96 km few-mode fiber it is found that the mode dependent loss is 3 dB, with negligible temporal fluctuations and almost no impact on capacity.
