DSP for Mode Division Multiplexing

2013 18th OptoElectronics and Communications Conference held jointly with 2013 International Conference on Photonics in Switching, 2013
We discuss possible architectures and complexity scaling of SDM interfaces that include multiple-input multiple-output digital signal processing (DSP) to deal with coupling between spatial and polarization modes.

On-Chip Mode-Division Multiplexer

CLEO: 2013, 2013
We demonstrate micron-scale on-chip mode-division multiplexing device with low crosstalk using add-drop silicon ring resonators array. We taper the bus waveguide width to selectively phase-match the different bus waveguide modes to the ring mode.

A Field Trial of Mode-Division Multiplexing

2014 IEEE Photonics Society Summer Topical Meeting Series, 2014
We present results of the first field trial ever to include a component of MDM. The demonstrated scenarios all confirm the possibility for a partial upgrade of legacy systems to few-mode technology.

Dynamic channel modeling for mode-division multiplexing

2016 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2016
We propose a dynamic channel model to describe time-varying polarization- and spatial-mode coupling in few-mode fibers caused by fast environmental perturbations. We employ the model to study the tracking performance of adaptive multi-input multi-output equalization algorithms.

Silicon mode multiplexer processing dual-path mode-division multiplexing signals

Optics Letters, 2016
Great strides have been made in the optical interconnect for a mode-division multiplexing (MDM) system. The mode multiplexer/demultiplexer (MUX/DEMUX) is the crucial component for the MDM system. We propose and demonstrate a scheme that is different from the reported multiplexing schemes, mode MUX that tackles dual-path MDM signals simultaneously and ...

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 ...

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.

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 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.

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.
