Bend-Insensitive Grapefruit-Type Holey Ring-Core Fiber for Weakly-Coupled OAM Mode Division Multiplexing Transmission

Journal of Lightwave Technology, 2020
We propose a bend-insensitive grapefruit-type holey ring-core fiber to support orbital angular momentum (OAM) modes. The large air domain in the cladding, results in a large refractive index contrast between the ring-core and the cladding, which makes ...

Demonstration of PLC-based six-mode multiplexer for mode division multiplexing transmission

2015 European Conference on Optical Communication (ECOC), 2015
We demonstrated a six-spatial-mode multiplexer using effective index matching and adiabatic mode transition. Six-mode multiplexing including the equal effective indices of LP 21 b and LP 02 was successfully achieved with a fabricated PLC on one chip.

Silicon mode multiplexer processing dual-path mode-division multiplexing signals

Optics Letters, 2016
Great strides have been made in the optical interconnect for a mode-division multiplexing (MDM) system. The mode multiplexer/demultiplexer (MUX/DEMUX) is the crucial component for the MDM system. We propose and demonstrate a scheme that is different from the reported multiplexing schemes, mode MUX that tackles dual-path MDM signals simultaneously and ...

A Flexible and Reconfigurable Optical Add-Drop Multiplexer for Mode Division Multiplexing Systems

IEEE Photonics Technology Letters, 2020
Reconfigurable 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 ...

Few-mode fibers for mode-division multiplexing

2013 IEEE Photonics Society Summer Topical Meeting Series, 2013
The design of few-mode fibers will be discussed from the point of view of key attributes and fundamental limitations. We will consider the maximum number of modes that might be supported in a practical fiber.

Mode-Division Multiplexing at Visible Wavelengths

Conference on Lasers and Electro-Optics
We demonstrate mode-division multiplexing at visible wavelengths (473 nm) for the first time using adiabatic mode couplers. We measure less than −15 dB and −20 dB crosstalk for TE2 and TE3 higher-order mode couplers, respectively.

Integrated mode converter for mode division multiplexing

SPIE Proceedings, 2016
The ever growing demands of bandwidth in optical communication systems are making traditional Wavelength Division Multiplexing (WDM) based systems to reach its limit. In order to cope with future bandwidth demand is necessary to use new levels of orthogonality, such as the waveguide mode or the polarization state.

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.
