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.

Wavelength-division multiplexing with femtosecond pulses
Optics Letters, 1995We 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.

Wavelength Division Multiplexing
SPIE Proceedings, 1985Wavelength division multiplexing (WDM) represents an approach for expanding the communication capacity and for implementing special data techniques in a fiber optics system. This technology is implemented by adding optical sources of different wavelengths at optical transmitting locations. The present paper is concerned with some of the current efforts

WAVELENGTH DIVISION MULTIPLEXED NETWORKS
Optical Amplifiers and Their Applications, 1995Wavelength-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.

Wavelength-Division Multiplexed Optical Cryptocurrency
Conference on Lasers and Electro-Optics, 2021We propose an optical proof-of-work scheme that feeds data encoded into wavelength-division multiplexed modes through a programmable photonic network. We verify robustness by modeling network dispersion, allowing for energy-efficient optical al- ternatives to current cryptocurrency security schemes.

Wavelength Division Multiplexing (WDM)
2021Wavelength division multiplexing or WDM allows the combining of a number of independent information-carrying wavelengths onto the same fiber, because of the wide spectral region in which optical signals can be transmitted efficiently. This chapter addresses the operating principles of WDM, describes a wide array of optical sources and passive ...

Multisoliton interactions and wavelength-division multiplexing
Optics Letters, 1995Multisoliton interactions are studied with an asymptotic expansion of the N-soliton solution in the limit of large frequency separation between the channels. In this limit the spectral distortion is small and the peak frequency shift of a channel is the sum of pairwise shifts as a result of interaction with other channels.
