Dynamic channel modeling for mode-division multiplexing
2016 IEEE Photonics Society Summer Topical Meeting Series (SUM), 2016We 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.

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 ...

Discrete Multitone Modulation for Short-Reach Mode Division Multiplexing Transmission
Journal of Lightwave Technology, 2019Spatial division multiplexing (SDM) can support the capacity demand increase in short-range optical link, but the communication is affected by the intermodal crosstalk. In order to target a low-cost energy-efficient solution, we propose to exploit direct

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), 2019In 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, 2015We 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.
