Abstract
We experimentally validate a complete optical packet switched interconnection
network, implementing the SPINet architecture. The scalable photonic integrated
network (SPINet) architecture capitalizes on wavelength division multiplexing
(WDM) to provide very large transmission bandwidths, simplify network design,
and reduce the network's power dissipation. Contention resolution is performed
in the optical domain, and a novel physical layer acknowledgement protocol
is employed to mitigate the associated latency and performance penalties.
Moreover, the SPINet architecture is specifically designed to enable on-chip
integration by not using any kind of optical delay lines. Experiments presented
include a complete functionality verification, error-free routing of 80Gb/s wavelength-striped optical packets (8 wavelengths each
modulated at 10 Gb/s) with a bit-error rate (BER) better than $10^{{-}12}$, and novel performance-enhancement
techniques such as path adjustments and load balancing.
