MIMO DSP Complexity in Mode-Division Multiplexing

Optical Fiber Communication Conference, 2015
We review group delay management techniques and multi-input multi-output (MIMO) digital signal processing (DSP) architectures for mode-division multiplexing systems. We demonstrate long-period fiber grating devices for introduction of strong mode coupling to obtain fast and low complexity MIMO DSP.

Photonic Lanterns for Mode Division Multiplexing

Asia Communications and Photonics Conference 2014, 2014
Photonic lanterns have been identified as a suitable technology for MDM. Photonic lanterns are mode converters with low loss, can introduce mode selectivity, can scale to many modes, and are easily integrated with current technologies.

Switching and Multiplexing Technologies for Mode-Division Multiplexed Networks

Optical Fiber Communication Conference, 2017
• Mode-multiplexing over multimode fibers has the potential to scale WDM networks by a factor of 10 or more • Multimode components like wavelength selective switches and optical amplifiers can scale to large number of modes • Wavelength selective switches, which are the basic building block for WDM network can be extended to support multimode fibers ...

Multiplexing and switching for mode division multiplexed optical interconnects

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
We present some basic functional elements for mode division multiplexed optical interconnects including an inverse designed mode multiplexer, a thermo-optic based mode add-drop switch, and integrated modulators for mode division multiplexed interconnects.

Equalizer complexity of mode-division multiplexed coherent receivers

2012 14th International Conference on Transparent Optical Networks (ICTON), 2012
We show that OFDM requires the lowest equalizer complexity for crosstalk compensation in a mode-division-multiplexing receiver. For a 2000-km transmission distance and less than 10% ODFM-specific overhead, the modal dispersion must be below 12 ps ...

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.

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.

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 ...

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.
