Optical millimeter wave mode division multiplexing of LG and HG modes for OFDM Ro-FSO system

Optics Communications, 2019
The scarcity of RF spectrum at lower frequencies has recently been addressed by millimeter wave transmission in fiber-wireless and radio-over-free-space optics networks for more flexible frequency spectrum allocation.

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.

First Demonstration of Polarization-Multiplexing Combined with On-Chip Mode-Division-Multiplexing

Optical Fiber Communication Conference, 2014
Polarization-multiplexed data is transmitted jointly with on-chip 2-mode mode-division-multiplexed data. Error-free operation and 5 dB of power penalty at an aggregate 40-Gb/s data rate are demonstrated, showing potential for pol-mux and mode-division-multiplexing networks on chip.

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.

On-Chip Mode-division Multiplexing with Modal Crosstalk Mitigation

Optical Fiber Communication Conference (OFC) 2020, 2020
We experimentally demonstrate modal crosstalk mitigation over an on-chip mode-division multiplexing link employing low-coherence matched detection. 20-Gbaud QPSK and 8-PSK mode-multiplexed signals are successfully transmitted with a maximum modal crosstalk of −6.5 dB.

Demonstration of bidirectional PON based on mode division multiplexing

2016 IEEE Photonics Conference (IPC), 2016
Recently, mode division multiplexing (MDM) has been introduced into optical transmission systems and networks for capacity enhancement. In this letter, we propose a bidirectional passive optical network (PON) architecture based on MDM. The bidirectional optical distribution network (ODN) of the MDM-PON consists of few-mode fiber, passive mode ...
