Abstract :
We present SPINet (Scalable Photonic Integrated Network), a novel optical packet switching architecture that is chiefly designed for implementation with photonic integrated circuit technology, where fiber delay lines cannot be employed. A novel physical layer acknowledgment protocol is introduced to mitigate the penalty associated with message dropping. The architecture´s concepts are described and the fabrication of a prototype semiconductor optical amplifier-based switching node is reported. Routing of 160-Gb/s (16×10 Gb/s) optically addressed messages with bit-error rates better than 10-12 and the successful back-propagating transmission of acknowledgment pulses are experimentally demonstrated.
