All-optical techniques enabling packet switching

Abstract

Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. After reviewing several labeling techniques, we discuss in this talk label stacking techniques and its benefits for scalable optical burst and packet switched nodes. All-optical signal processing techniques enabling label stacked processing and all-optical devices for ultrafast packet switching will be also presented.
