Standardization of optical frequencies for wavelength-division-multiplexing (WDM) networking applications

SPIE Proceedings, 1995
We describe new requirements for a frequency reference in terrestrial line systems using wavelength division multiplexing and optical amplifiers, and evaluate leading atomic or molecular references for suitability.

Code division multiple access (CDMA) enhancement of wavelength division multiplexing (WDM) systems

Proceedings IEEE International Conference on Communications ICC '95, 2002
Wavelength division multiplexing (WDM) is a mainstream technology for optical communications ranging from long haul applications to interconnections between and within high speed digital systems. WDM is, however, constrained (1) in density by the crosstalk associated with channel spacing and (2) by total number of channels which can be uniformly ...

Routing, wavelength and time-slot assignment in time division multiplexed wavelength-routed optical WDM networks

Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2003
We study routing and wavelength assignment for a circuit-switched time division multiplexed (TDM) wavelength-routed (WR) optical WDM network. In a conventional WR network, an entire wavelength is assigned to a given session (or circuit). This can lead to lower channel utilization when the individual sessions do not need the entire channel bandwidth. We

Bandwidth Reduction Technique for Multilayer Wavelength Division Multiplexing (WDM) Bandpass Filters

Applied Optics, 2000
The push to develop 100 GHz and smaller bandwidth WDM filters is at demanding levels. Currently, 200 GHz is the standard bandwidth for multilayer interference coatings with high efficiencies, and enormous processing effort is going into the development of standard 100 GHz filters. This paper outlines a simple design that will reduce bandwidth up to 40%
