Cognitive Routing in Converged Access-Metro Environment via
-Selective SOA-MZI Switch
A ring+tree architecture for optical intranetwork data transmission between different users is presented. The nodes at the ring contain a packet envelope detection to extract a wavelength-dependent control signal for a semiconductor optical amplifier-based Mach-Zehnder interferometer (SOA-MZI) switch. The scalability of the architecture and the feasibility for field deployment are discussed. A tree split of 1:1000 has been found to be compatible with data transmission over 50 hops.
