All-optical LAbel-SwApping employing optical logic G ates in NEtwork nodes
[January 2004 – December 2006]

PCRL participated in the LASAGNE project that aimed at studying, proposing and validating the use of all-optical logic gates and optical flip-flops based on commercially-available technologies to implement the required functionalities at the metro network nodes in All-optical label swapping (AOLS) networks. The optical gates were implemented using the same key building block: SOA-based Mach-Zehnder interferometers (MZIs). A functional photonic router prototype incorporating all-optical label swapping and wavelength conversion was integrated using optical logic gates and optical flip-flops. This photonic router was designed to be modular, scalable, and with potential for system integration.
