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.

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.

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 ...

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.

Mode-Division Multiplexer with Contra-directional Couplers

2019 24th OptoElectronics and Communications Conference (OECC) and 2019 International Conference on Photonics in Switching and Computing (PSC), 2019
In this paper, a mode-division multiplexer is numerically designed using 2D Finite Difference Time Domain (FDTD) method that can multiplex three modes simultaneously by employing gratings, which enable power transfer between the waveguide modes.

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.

Silicon-on-Insulator Mode (de)Multiplexer for On-Chip Mode-Division Multiplexing

Asia Communications and Photonics Conference 2013, 2013
We propose a simple 1×4 silicon mode (de)multiplexer based on multimode grating-assisted-couplers. Due to the contra-directional coupling, precise control of the coupling strength and the coupling length are not needed.

Spatial multiplexers and demultiplexers for mode group division multiplex

2013 15th International Conference on Transparent Optical Networks (ICTON), 2013
Spatial multiplexer and demultiplexer are beneath the multimode fiber the key components for a transmission system using mode or mode group division multiplexing (MDM or MGDM). The spatial multiplexer converts the LP01 modes of the incoming singlemode fibers into the desired modes or mode groups of the multimode fiber.
