Silicon-based four-mode division multiplexing for chip-scale optical data transmission in the 2  μm waveband

Photonics Research, 2019
Based on a silicon platform, we design and fabricate a four-mode division (de)multiplexer for chip-scale optical data transmission in the 2 μm waveband for the first time, to the best of our knowledge.

Holographic Mode-Group Division Multiplexing

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2011, 2011
Specific fibre modes are deliberately excited in a few-mode and multimode fibre using holography. The same system is also used to demonstrate holography's ability to detect and route individual fibre modes.

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.

Adaptive MIMO Signal Processing for Mode-division Multiplexing

Optical Fiber Communication Conference, 2012
The fiber-optic multiple-input multiple-output (MIMO) channel is analyzed. For a 6×6 MIMO experiment over 96 km few-mode fiber it is found that the mode dependent loss is 3 dB, with negligible temporal fluctuations and almost no impact on capacity.

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.
