Space-division multiplexing in optical fibres

Nature Photonics, 2013
This Review summarizes the simultaneous transmission of several independent spatial channels of light along optical fibres to expand the data-carrying capacity of optical communications.

Wavelength division multiplexed systems and networks [PDF]

Proceedings of LEOS '93, 2002
Summary form only given. Optical Wavelength Division Multiplexing (WDM) has emerged as an extremely flexible and efficient technique for accessing the vast optical fiber bandwidth. It also allows the provision of various services and flexible upgrading in optical networks.

Frequency-Division Multiplexing and Main Peak Scanning WMS Method for TDLAS Tomography in Flame Monitoring

IEEE Transactions on Instrumentation and Measurement, 2020
The wavelength modulation spectroscopy (WMS) method is typically used in the tunable diode laser absorption spectroscopy (TDLAS) for spectrum extraction in a noisy background.

Enabling Technologies for Optical Data Center Networks: Spatial Division Multiplexing

Journal of Lightwave Technology, 2020
With the continuously growing popularity of cloud services, the traffic volume inside the data centers is dramatically increasing. As a result, a scalable and efficient infrastructure for data center networks (DCNs) is required.

Wavelength division multiplexing of dispersion managed solitons

24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002
Periodic dispersion compensation largely widens the transmission bandwidth of solitons with enhanced power. Soliton interactions and collisions in a wavelength-division-multiplexed system may however set important limitations to the channel spacing.

Multichannel wavelength division multiplexing with photonic crystals

Applied Optics, 2001
A multichannel wavelength-division-multiplexing system consisting of a two-dimensional photonic crystal is proposed. The system consists of two parts, a waveguiding element, realized by defects in a photonic crystal, and frequency-selective elements, realized by photonic crystal microcavities.

Chaotic wavelength division multiplexing for optical communication

Optics Letters, 2004
We demonstrate wavelength division multiplexing with chaotic subcarriers in two pairs of one-way-coupled Nd:YVO4 microchip lasers. Two individual digital messages are encoded on two chaotic carriers with different wavelengths in two transmitters by the chaotic masking method, and the mixed signals are sent to two receivers.

Stabilization of Soliton Wavelength-Division-Multiplexed Transmissions

Nonlinear Guided Waves and Their Applications, 1996
In this work, we consider the bandwidth limitations in soliton wavelength-division-multiplexed (WDM) transmission systems [1, 2]. The present analysis suggests different methods to overcome two of the main sources of instability that limit the available optical bandwidth, namely third-order dispersion (TOD) and resonant soliton-soliton collisions [6, 4,

The wavelength division multiplexers for optical telecommunication

Journal of Optics, 1984
Examples of wavelength division multiplexers using multidielectric filters, gratings or both of them, published by different authors, are given. The filter devices are well adapted to the multiplexing of a small number of channels with large distances between wavelengths.

Optical Processor With Wavelength Division Multiplexing

SPIE Proceedings, 1984
We designed an optical processor using wavelength division multiplexing which performs matrix-vector and matrix-matrix multiplications. The Wavelength Division Multiplexing (WDM) Optical Processor can perform analog and digital operations. Its principal advantage over other processors is its parallel architecture that enables high speed calculations.© (
