In this paper, we address the experimental implementation of an all-optical packet routing scheme, with contention resolution capability, using interconnected semiconductor optical amplifier (SOA)-based Mach?? Zehnder interferometer (SOA-MZI) structures. Cross talk stemming from the blocked packets, due to the nonideal switching performed by the SOA-MZIs, is analyzed in every stage of the routing...
Continuously tunable, optically-controlled variable delay line based on dynamic Brillouin grating is exploited for automated synchronization of switching signals in a network node, enabling asynchronous contention resolution with packet priorization.
Elementary blocks, performing basic operations, are the building elements for complex subsystems implementing all-optical digital processing. They can enable next generation optical networks and optical computing overcoming electronic issues as bandwidth and power consumption.
An all-optical, integrable, ultra-fast 2times2 spatial switch based on cross-gain-modulation in semiconductor optical amplifiers able to process signals up to 160 Gbit/s is demonstrated. Penalty measurements confirm the effectiveness of the proposed scheme in cascade configurations.
