Abstract

The high bandwidth of optical fibers and photonic switching devices offers the potential to increase the usable bandwidth in packet switched networks and interconnects. In this paper we describe several methods to code packetized information using both the time and optical frequency domains. The presence or absence of optical power at discrete optical wavelengths is treated as units of information, resulting in two-dimensional coded packets which may be processed using novel, perhaps more efficient routing architectures. We describe three basic codes and their corresponding routing processor architectures. Several new logic primitives are introduced including optical set logic and lambda-gates. The resulting information capacities for these codes and the associated routing processor complexity, and efficiency in terms of number of mappings per gate are discussed.
