Mode division multiplexed networks
2017 Opto-Electronics and Communications Conference (OECC) and Photonics Global Conference (PGC), 2017A 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, 2013We 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.

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.

Wavelength selective mode division multiplexing on a silicon chip
Optics Express, 2015 Multiplexing of optical modes in waveguides is demonstrated using coupled vertical gratings. The device utilizes sinusoidally corrugated waveguides of different widths with a period designed to multiplex information at 1.55 µm. The design, fabrication and characterization of devices is performed.

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.

Equalizer complexity of mode-division multiplexed coherent receivers
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012We show that OFDM requires the lowest equalizer complexity for crosstalk compensation in a mode-division-multiplexing receiver. For a 2000-km transmission distance and less than 10% ODFM-specific overhead, the modal dispersion must be below 12 ps ...
