“…The system shown in Figure 2 was demonstrated using the described monolithic PFCs and evaluated using both Layer 1 and Layer 2 performance metrics. Layer 1 was demonstrated with error free operation while Layer 2 showed header recovery loss and packets switch throughput of over 90% ( Figure 3) [2]. These results show the fundamental success of the core of the switch, but without buffering.…”

“…However, the migration scenario of optical systems has been recently redefined, and in the near future both alloptical and electrical signal processing are expected to coexist [3,4]. In this new inwards penetration path depicted in Figure 1, header extraction is currently at the forefront of all-optical processing subsystems, as it will allow the payload to remain in the optical domain, while header processing could be treated electrically.…”

“…Considerable work on OLS labeling has been also reported for coding low-rate labels in different modulation [2] using customized transmitter designs. Up to now, packet routing with lower bit-rate labels has been reported, ranging from megabits per second up to 10-Gb/s labels [3], [4]. In the last years, research on all-optical signal processing has been fueled through research projects [6]- [8] and the creation of companies offering integrated devices.…”

Abstract-In this letter, we demonstrate that all-optical network subsystems, offering intelligence in the optical layer, can be constructed by functional integration of integrated all-optical logic gates and flip-flops. In this context, we show 10-Gb/s all-optical 2-bit label address recognition by interconnecting two optical gates that perform XOR operation on incoming optical labels. We also demonstrate 40-Gb/s all-optical wavelength-switching through an optically controlled wavelength converter, consisting of an integrated flip-flop prototype device driven by an integrated optical gate. The system-level advantages of these all-optical subsystems combined with their realization with compact integrated devices, suggest that they are strong candidates for future packet/label switched optical networks. IndexTerms-Address recognition, Mach-Zehnder interferometer (MZI), optical flip-flop, optical label swapping (OLS), packet switching, semiconductor optical amplifier (SOA), wavelength conversion.
