On-chip multiplexing conversion between wavelength division multiplexing–polarization division multiplexing and wavelength division multiplexing–mode division multiplexing

Optics Letters, 2014
A compact silicon-on-insulator device used for conversions between polarization division multiplexing (PDM) and mode division multiplexing (MDM) signals is proposed and experimentally demonstrated by utilizing a structure combining the improved two-dimensional grating coupler and two-mode multiplexer.

Mode division multiplexing in optical fibers

Applied Optics, 1982
Two modes have been launched into a conventional 10-m long multimode graded-index optical fiber using spatial filtering techniques. The measured cross talk between the two modes in the baseband is -20 dB at the output end of the fiber. Modal multiplexing thus appears to be possible over short fiber lengths.

Fiber-Chip Link via Mode Division Multiplexing

IEEE Photonics Technology Letters, 2023
Applying mode division multiplexing techniques to a fiber-chip link would greatly increase its communication bandwidth. However, its implementation is very difficult due to the huge higher-order mode mismatch between multimode integrated waveguides and ...

Perspective on mode-division multiplexing

Applied Physics Letters, 2021
We review the current status of mode-division multiplexing (MDM) techniques in fibers and on chips. Three system applications are introduced, including quasi-single mode transmission, multicore few-mode amplifier, and fiber sensing. We also discuss the technology development trend in terms of multiple-input-multiple-output-free MDM, economics of MDM ...

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.

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.
