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.
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.
A modular photonic interconnection network based on a combination of basic 2times2 all-optical nodes including a photonic combinatorial network for the packet contention management is presented. The proposed architecture is synchronous, can handle optical time division multiplexed (OTDM) packets up to 160 Gb/s, exhibits self-routing capability, and very low switching latency. In such a scenario, OTDM...
A photonic 2x2 node architecture for synchronous all-optical packet switching networks, able to process ultra-fast packet signals is presented. All node functions (label recognition and processing, contention detection and resolution, switch control, actual switching, and regeneration) are optically performed. Combinations of the proposed 2times2 element can be used in order to obtain more complex...
