The integration of the storage of optical data using fiber loops and extremely rapid optical based switching via nonlinear optical loop mirrors (NOLMs) are recognized as an optimal approach for all-optical processing. This article presents a novel integration of these technologies to create an efficient buffering-switching device aimed at mitigating signal contention. Through thorough analysis, we explore the limitations of this integrated device in achieving error-free processing across multiple buffering cycles. Various factors, such as different types of noise leading to fluctuations in intensity of buffered and demultiplexed signals, are assessed. Additionally, we delve into the switching characteristics of NOLM demultiplexer to provide a comprehensive understanding of the device's performance.
This research examined the optimum requirements for revamping virtual topology for wavelength-routed networks under dynamic traffic demand for mesh physical topology networks. We analysed the optimization of congestion and entire output using the Yen’s K-shortest path algorithm, which is a new approach to investigate the optimum condition for transmission according to time and the number of users. We also consider energy usage during optimal path selection. Previous studies have primarily focused on providing configuration strategies exclusively for selected light paths, with limited consideration for the overall physical topology configuration. Contrarily, the method proposed in this paper can be applied to optimize light path scenarios across various physical topologies.
