Experimental Demonstration of an Elastic Packet Routing Node Based On OCDMA Label Coding
Résumé
we propose and demonstrate experimentally an alloptical
packet routing scheme using hybrid wavelength division
multiplexing/optical code division multiple access labeling for 40
Gb/s NRZ data. With no electronic control, the system forwards
asynchronously packets delimited by valid label and suppresses
unwanted traffic. It consists in an optical flip-flop controlled by
two correlators combined with a Mach-Zehnder interferometer
that selects packets for each fiber output. The experimental
results show optical switching operation for the optical-code gate
with an extinction ratio of 16 dB between the switched and
un-switched packets in a switching time below 2 ns. Error-free
operation has been successfully achieved with low power penalty
for 40 Gb/s NRZ data.
