We present an Optical Interface Message Processor (OPTIMP) that exploits the high bandwidth, parallelism, multidimensional capability, and high storage density offered by optics. Switching and routing functions are performed in the optical domain and thus OPTIMP does not suffer from the optical/electronic conversion bottleneck associated with current fiber optics networks. The source-destination (SD) information from a message is first converted to the spatial domain. The routing table stores all SD codes and the corresponding control codes for setting the switching network, The routing table is searched in parallel and control signals corresponding to the matched SD code are readout to configure the network. The optical implementation is based on S-SEED array technology. The power requirements and performance of OPTIMP based on the current technology are analyzed.
