A Self-Routing Opitcal Interconnect Network Based on Holographic Associative Memory

Physical Optics Corporation (POC) proposes a new self-routing technique which provides solutions to switching contention and multi-stage routing problems encountered by the conventional self- routing techniques such as TDM, WDM and CDM. Furthermore, a fiber optic delay line memory is introduced to eliminate the time synchronization and temporary storage problems of fiber optic data packet switching networks. As a result, three key devices are needed in the implementation of a self-routing network node. In addition to the fiber optic delay line memory, an optical switching array is used for data switching, and a digital optical associative memory (DOAM) is used as a self-routing switching controller. An engineering development model will be constructed in the Phase I program to demonstrate the key features of the proposed approach and its potential for use in high-speed self- routing networks.
