The potential of incorporating electronically controlled photonic switching components in fiber-optic ring-based communication networks is explored. Possible extensions to fiber ring architectures with lithium niobate switches are proposed, and potential problems that limit wide-scale use of these devices are identified. The use of 2*2 directional couplers to provide faulty node bypass is investigated. This concept is extended to larger photonic switches with multiple fibers to provide higher throughput. This approach also provides multiple redundant paths that enable the network to be reconfigured based on traffic demands and faults on the ring. The concept of distributing switching capabilities among all the nodes in a network is introduced. Two networks with distributed switching capabilities are examined. Switching parameters that impact the application of photonic devices in ring networks are discussed.>
