Wavelength-selective switching is generally considered to be an essential element for building agile “all optical” mesh telecommunications networks. This paper will provide an overview of the various node architectures suitable for implementing such networks. It will also provide an overview of the various technologies, that have been developed for such networks, including integrated optical waveguide circuits and free-space optical devices. While these technologies were largely developed for telecommunications applications, they may also applicable for computer networks.
