Multisoliton interactions and wavelength-division multiplexing

Optics Letters, 1995
Multisoliton 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.

Time-Division-Multiplexing–Wavelength-Division-Multiplexing-Based Architecture for ONoC

Journal of Optical Communications and Networking, 2017
Future many-core processors will require high-performance yet energy-efficient on-chip networks to provide a communication substrate for the continually increasing number of cores on one chip. Optical networkon- chip (ONoC) is employed as a promising candidate interconnection solution for its high bandwidth and low energy consumption.

Compact wavelength division multiplexers and demultiplexers

Applied Optics, 2002
Compact devices for wavelength division multiplexing and demultiplexing, believed to be novel, are presented. These devices are based on planar optics configurations, comprising multiplexed diffractive optical elements. The principle, design, and recording of these planar devices are described, including the fact that the recording is done at a single ...

Wavelength Division Multiplexing

SPIE Proceedings, 1985
Wavelength 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, 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.

Routing and Wavelength Assignment in Wavelength Division Multiplexing Networks

2004
The problem of wavelength routing and assignment (WRA) to lighpaths in a multi-hop wavelength division multiplexed (WDM) optical network has been addressed in this paper. The wavelength assignment problem has been solved by mapping it to a heuristic based clique partitioning problem.

Wavelength Division Multiplexing (WDM)

2021
Wavelength 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 ...

Optical wavelength division multiplex

[Proceedings] GLOBECOM '90: IEEE Global Telecommunications Conference and Exhibition, 2002
The 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). >

A multiplexer/demultiplexer for coarse wavelength-division multiplexing

Technical Physics Letters, 2004
Increasing 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 ...

Optical demultiplexer for a wavelength division multiplexing system

Applied Optics, 1979
A wavelength division multiplexing (WDM) technique, which transmits signals with different wavelengths by means of a single optical fiber, can increase the capacity of optical fiber transmission systems. This paper describes the experimental results of a demultiplexer using a diffraction grating for a WDM system. The insertion loss of the demultiplexer
