Degenerate Mode-Group Division Multiplexing

Journal of Lightwave Technology, 2012
A reconfigurable mode demultiplexer based around a liquid crystal spatial light modulator is demonstrated to optically demultiplex modes that share a propagation constant as separate modal channels using a single shared phase mask per polarization for all channels.

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.

Wavelength and polarization division multiplexing using the LP11 mode in a two-mode fiber for mode division multiplexing

SPIE Proceedings, 2011
The orthogonality of Mode Division Multiplexing (MDM) with Wavelength division multiplexing (WDM) and Polarization Division Multiplexing (PDM) is investigated applying WDM and PDM transmission over the LP11 mode in a few-moded fiber. Two wavelengths, each carrying 10Gbit/s signals in two orthogonal polarizations are successfully transmitted with the ...

Ultracompact terahertz plasmonic mode division multiplexer

Optics Letters, 2023
In this Letter, an ultracompact terahertz (THz) mode division multiplexer based on THz spoof surface plasmon polaritons (SPPs) is proposed. Compared with traditional optical multiplexing devices, the proposed mode multiplexer can be designed with a reduced footprint by exploiting more degrees of freedom in the parameters of the unit cell, namely a ...

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.

Mode division multiplexed networks

2017 Opto-Electronics and Communications Conference (OECC) and Photonics Global Conference (PGC), 2017
A deployment scenarios of space division multiplexing (SDM) in metro area network is presented. Comparative studies of few-mode fiber vs. multicore fiber as well as mode division multiplexed (MDM) node architectures of supermode vs. mode-unbundling are discussed.

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.

Spatial Mode Division Multiplexing of Few Mode Fiber

European Conference and Exhibition on Optical Communication, 2012
The independent excitation and detection of spatial modes in few-mode fiber networks presents major challenges. This paper presents novel spatial mode-division-multiplexing techniques based on planar couplers and asymmetric Y-junctions. These developments may play a role in future high-capacity few-mode fiber telecommunications.

Demonstration of PLC-based six-mode multiplexer for mode division multiplexing transmission

2015 European Conference on Optical Communication (ECOC), 2015
We demonstrated a six-spatial-mode multiplexer using effective index matching and adiabatic mode transition. Six-mode multiplexing including the equal effective indices of LP 21 b and LP 02 was successfully achieved with a fabricated PLC on one chip.

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 ...
