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.

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 ...

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.

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.

Few-mode fibers for mode-division multiplexing

2013 IEEE Photonics Society Summer Topical Meeting Series, 2013
The design of few-mode fibers will be discussed from the point of view of key attributes and fundamental limitations. We will consider the maximum number of modes that might be supported in a practical fiber.

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 ...

Integrated mode converter for mode division multiplexing

SPIE Proceedings, 2016
The ever growing demands of bandwidth in optical communication systems are making traditional Wavelength Division Multiplexing (WDM) based systems to reach its limit. In order to cope with future bandwidth demand is necessary to use new levels of orthogonality, such as the waveguide mode or the polarization state.
