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.

Silicon-Based Hybrid (de)Multiplexer for Wavelength-/Polarization-Division-Multiplexing

Journal of Lightwave Technology, 2018
A novel hybrid multiplexer for wavelength-division- multiplexing (WDM) and polarization-division-multiplexing (PDM) is proposed and realized by integrating a polarization-splitter-rotator (PSR) and an optical-filter array based on novel microring ...

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 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 ...

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 ...

Wavelength-Division Multiplexed Optical Cryptocurrency

Conference on Lasers and Electro-Optics, 2021
We 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, 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). >

Optical fiber wavelength division multiplexing

IEEE Aerospace and Electronic Systems Magazine, 2003
During flight, aircraft avionics transmit and receive RF signals to/from antennas over coaxial cables. As the density and complexity of onboard avionics increases, the electromagnetic interference (EMI) environment degrades proportionately, leading to decreasing signal-to-noise ratios (SNRs) and potential safety concerns.
