Architecture and devices for an all-optical routing switch

Ultra-high-speed optical communication networks will require routing switches which support data rates beyond the capabilities of optical-electronic conversion. This paper describes the preliminary design of an `all-optical' routing switch for a network in which data messages remain in optical form throughout the transmission from source to destination. The basic switch architecture and fundamental design trade-offs affecting switch implementation are discussed. Characteristics of the optical device technology required to implement the routing switch elements are also presented.
