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.

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.

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.

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 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 ...

A multiplexer/demultiplexer for coarse wavelength-division multiplexing
Technical Physics Letters, 2004Increasing the transmission capacity of existing and newly developed optical communication lines and networks (data exchange systems) implies the use of wavelength-division multiplexing (WDM). Optical fiber multiplexers and demultiplexers are the WDM devices necessary for combining several carriers in a common optical tract and performing the inverse ...

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.

Optical wavelength division multiplex
[Proceedings] GLOBECOM '90: IEEE Global Telecommunications Conference and Exhibition, 2002The author presents a brief overview of WDM (wavelength division multiplexing) technology, systems, and challenges, with emphasis on current research at AT&T Bell Laboratories. Particular attention is given to long-haul systems, local applications, and tunable WDM (e.g. the WDM digital crossconnect system and WDM multiple-access networks). >
