Equalizer complexity of mode-division multiplexed coherent receivers

2012 14th International Conference on Transparent Optical Networks (ICTON), 2012
We 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 ...

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.

Multimode Fibers for Mode Division Multiplexing

Conference on Lasers and Electro-Optics, 2017
Graded-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.

On-chip mode division multiplexing technologies

SPIE Proceedings, 2016
Space division multiplexing (SDM) is currently widely investigated in order to provide enhanced capacity thanks to the utilization of space as a new degree of multiplexing freedom in both optical fiber communication and on-chip interconnects. Basic components allowing the processing of spatial modes are critical for SDM applications.

High-Capacity Mode Division Multiplexing Transmission Technology

Optical Fiber Communication Conference (OFC) 2022, 2022
Mode division multiplexing is an attractive method of increasing the transmission capacity. This paper presents the 402.7-Tbit/s weakly coupled 10-mode-multiplexed transmission over 48 km and 50.47-Tbit/s standard cladding coupled 4-core fiber transmission over 9,150 km.

Bidirectional mode-division multiplexers with antireflection gratings

Applied Optics, 2018
A 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 ...

Multiplexing and switching for mode division multiplexed optical interconnects

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
We 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.

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 Mode Division Multiplexing of Few Mode Fiber

European Conference and Exhibition on Optical Communication, 2012
The independent excitation and detection of spatial modes in few-mode fiber networks presents major challenges. This paper presents novel spatial mode-division-multiplexing techniques based on planar couplers and asymmetric Y-junctions. These developments may play a role in future high-capacity few-mode fiber telecommunications.

Optical Amplifiers for Mode Division Multiplexing

2018
Space division multiplexing (SDM) has attracted considerable attention from the optical fiber communication community as a promising means to increase the transmission capacity per fiber and, more importantly, to reduce the associated cost per transmitted information bit by utilizing multiple spatial channels within a single strand of glass.
