چکیده :

In this paper, optical routers play an indispensable role in the ONoCs. 4×4, 5×5, and scalable optical routers based on Mach-Zehnder Interferometer (MZIs) and micro-ring resonator (MRRs) are proposed. These routers are designed for a deadlock-free Odd-Even turning model. The four- and five-port and scalable optical routers are extended to improve network performance and physical-layer parameters for a broad range of silicon nano-photonic multicore interconnection topologies. Compared to previously reported router designs, these router designs allow quantifying improved system performance parameters in terms of insertion loss for well-known photonic interconnection topologies. The simulation results show that Odd-Even MRR- based four- and five-port optical routers outperform conventional routers in network performance parameters. For instance, the insertion loss of these optical routers in the mesh topology show 30.22% and 68.40% improvement compared to conventional routers. The routing performance of this router is simulated by the successful transmission of a 20-Gbps optical signal at the wavelength of 1552 nm for each qualified port from a choice of physical paths. Moreover, the growth of the number of MRR used in the structure of Odd-Even scalable router design per N I/O ports has been significantly reduced compared to previous scalable MRR-based designs.
