On-chip multiplexing conversion between wavelength division multiplexing–polarization division multiplexing and wavelength division multiplexing–mode division multiplexing

Optics Letters, 2014
A compact silicon-on-insulator device used for conversions between polarization division multiplexing (PDM) and mode division multiplexing (MDM) signals is proposed and experimentally demonstrated by utilizing a structure combining the improved two-dimensional grating coupler and two-mode multiplexer.

Diversity-multiplexing tradeoff in mode-division multiplexing [PDF]

Optics Letters, 2014
The capacity of mode-division multiplexing (MDM) systems is limited, for a given outage probability, by mode-dependent loss (MDL) and gain. Modal degrees of freedom may be exploited to increase transmission rate (multiplexing gain) or lower outage probability (diversity gain), but there is a fundamental tradeoff between the achievable multiplexing and ...

OAM mode-division multiplexing IM/DD transmission at 4.32 Tbit/s with a low-complexity adaptive-network-based fuzzy inference system nonlinear equalizer.

Optics Letters, 2023
Stochastic nonlinear impairment is the primary factor that limits the transmission performance of high-speed orbital angular momentum (OAM) mode-division multiplexing (MDM) optical fiber communication systems.

Mode division multiplexing in optical fibers

Applied Optics, 1982
Two modes have been launched into a conventional 10-m long multimode graded-index optical fiber using spatial filtering techniques. The measured cross talk between the two modes in the baseband is -20 dB at the output end of the fiber. Modal multiplexing thus appears to be possible over short fiber lengths.

Single-wavelength polarization- and mode-division multiplexing free-space optical communication at 689 Gbit/s in strong turbulent channels.

Optics Letters, 2023
We experimentally demonstrated, for, it is believed, the first time, high-capacity polarization- and mode-division multiplexing free-space optical transmission with adequate strong turbulence resiliency.

Mode-division multiplexed transmission of wavelength-division multiplexing signals over a 100-km single-span orbital angular momentum fiber

Photonics Research, 2020
We experimentally demonstrate mode-division multiplexed (MDM) transmission using eight orbital angular momentum (OAM) modes over a single span of 100-km low-attenuation and low-crosstalk ring-core fiber (RCF).

High Power-Efficiency, Low DMG Cladding-Pumped Few-Mode Er/Yb/P Co-Doped Fiber Amplifier for Mode Division Multiplexing

Journal of Lightwave Technology, 2022
Mode division multiplexing (MDM) is considered to be an efficient solution to alleviate the exponentially increasing “capacity crunch”. Here, we numerically and experimentally demonstrate a high power-efficiency, low differential mode gain (DMG) few-mode

High-Capacity Mode Division Multiplexing Transmission Technology

Optical Fiber Communications Conference and Exhibition, 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 ...

Mode division multiplexing: from photonic integration to optical fiber transmission [Invited]

Chinese Optics Letters (COL), 2021
To overcome the capacity crunch of optical communications based on the traditional single-mode fiber (SMF), different modes in a few-mode fiber (FMF) can be employed for mode division multiplexing (MDM).

Degenerate Mode-Group Division Multiplexing

Journal of Lightwave Technology, 2012
A reconfigurable mode demultiplexer based around a liquid crystal spatial light modulator is demonstrated to optically demultiplex modes that share a propagation constant as separate modal channels using a single shared phase mask per polarization for all channels.
