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.

Ultra-Dense Wavelength-Division Multiplexing With Microring Modulator

Journal of Lightwave Technology, 2021
Silicon photonics can be used to increase the versatility of wavelength division multiplexing (WDM). Ultra-dense wavelength division multiplexing (uDWDM) shrinks channel spacing between WDM channels to decrease guard bands and increase spectral ...

Wavelength-division multiplexing with femtosecond pulses [PDF]

Optics Letters, 1995
We demonstrate wavelength-division multiplexing with a single broadband femtosecond source by slicing the 3.7-THz spectral bandwidth of 85-fs laser pulses into 16 channels that are modulated individually.

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).

WAVELENGTH DIVISION MULTIPLEXED NETWORKS

Optical Amplifiers and Their Applications, 1995
Wavelength-division-multiplexing (WDM) or optical frequency-division-multiplexing (OFDM) based transport networks are being intensively studied because they are expected to support broadband services [1-4]. Both transmission line capacity and processing node capacity will be increased by the simple node configuration.

Photonic nanostructures for wavelength division multiplexing [PDF]

SPIE Proceedings, 2004
The high angular dispersion achieved with the photonic crystal superprism effect as well as dispersive non-periodic photonic nanostructures promise compact wavelength division multiplexing (WDM) devices. An important criterion for the usefulness of such WDM devices is the number of channels that a structure can multiplex or demultiplex.
