Optical logic for network nodes

Tim Deegan
As optical transmission technology increases the available communications bandwidth, traditional router and switch designs have been unable to keep pace. One approach which has been suggested for solving this problem is the use of high-speed optics in the core routers and switches, replacing some of the functions performed by electronics today. While most of this research is aimed at replacing only the data-path components, in the longer term it may be feasible to replace control-path elements as well, using all-optical logic.

This talk will present an overview of the kinds of optical logic gates which could be used for such an approach, and a brief look at how they can be used.
