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 ...

Multiplexing and switching for mode division multiplexed optical interconnects
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016We present some basic functional elements for mode division multiplexed optical interconnects including an inverse designed mode multiplexer, a thermo-optic based mode add-drop switch, and integrated modulators for mode division multiplexed interconnects.

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 ...

A Flexible and Reconfigurable Optical Add-Drop Multiplexer for Mode Division Multiplexing Systems
IEEE Photonics Technology Letters, 2020Reconfigurable optical add-drop multiplexer (ROADM) is one of the key building blocks for on-chip optical networks, which can download the desired signals from the bus waveguide to the corresponding drop port and upload the local signals from the add ...

50 μm Multimode Fibers for Mode Division Multiplexing
Journal of Lightwave Technology, 201650-μm-diameter graded-index core multimode fibers can be adapted to mode-division-multiplexed transmissions that use multiple-input-multiple-output digital signal processing and selective mode multiplexing. We realize and characterize such fibers and compare them to low-differential-mode-group-delay few-mode fibers.

Multimode Fibers for Mode Division Multiplexing
Conference on Lasers and Electro-Optics, 2017Graded-index-core multimode fibers can be appropriately rescaled in diameters and optimized to have low differential mode group delays for 6 to 36 spatial modes for multiple-input-multiple-output mode-division-multiplexed transmissions.

Bidirectional mode-division multiplexers with antireflection gratings
Applied Optics, 2018A bidirectional mode-division multiplexer (BMDM) with antireflection gratings is designed, and its performance in terms of S-parameters is presented. A BMDM can (de)multiplex three modes with only two waveguides and a Bragg grating. The impact of return losses on the performance of BMDMs is studied and antireflection gratings are designed to reduce ...

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
