Switches, Wavelength Routers, and Wavelength Converters
2005This chapter introduces some of the basic components in WDM networks, discusses various implementations of these components, and provides insights into their capabilities and limitations. The components discussed are fixed and reconfigurable wavelength routers, optical packet switches, and wavelength converters.

Proceedings of INFOCOM '94 Conference on Computer Communications, 2002
The authors present a heuristic algorithm for effectively assigning a limited number of wavelengths among the access stations of a multihop network wherein the physical medium consists of optical fiber segments which interconnect wavelength-selective optical switches.

Applied Optics, 1973
Previous methods of two-wavelength variable-sensitivity interferometry are reviewed and a simplified two-wavelength technique for interferometric testing under static conditions is discussed. An extension of the static technique to real-time dynamic testing is proposed and an operational variable-sensitivity interferometer utilizing the real-time ...

Wavelength Division Multiplexers and the Measurement of the Channel Wavelengths
1995In the first part in the paper, we review different WDM integrated optics devices: in lithium niobate, on glass, on silicon or InP subtrates. It is shown that the main problem to be solved, in most of the cases, is the wavelength and transmission sensitivity to polarisation.

Two years ago we set out to design and build a wavelength meter [1] that would complement our tunable source research. [2] The design goals were a device that measured wavelengths for both pulsed and cw lasers, displayed single pulse laser bandwidths, used inexpensive broadband optics and could be interfaced with a minicomputer.
