Experimental analysis of an all-optical packet router
Reis, C.; Parca, G.; Bougioukos, M.; Maziotis, A.; Pinna, S.; Giannoulis, G.; Brahmi, H.; André, P.; Calabretta, N.; Vercesi, V.; Berrettini, G.In this paper, we address the experimental implementation of an all-optical packet routing scheme, with contention resolution capability, using interconnected semiconductor optical amplifier (SOA)-based Mach-Zehnder interferometer (SOA-MZI) structures. Cross talk stemming from the blocked packets, due to the nonideal switching performed by the SOA-MZIs, is analyzed in every stage of the routing configuration. T...
Performance comparison of all-optical clocked S-R and D type flip-flops
Reis, C.; Maziotis, A.; Kouloumentas, C.; Chattopadhyay, T.; Calabretta, N.; André, P.; Berrettini, G.; Meloni, G.; Bogoni, A.; Dorren, H. J. S.In this paper, different approaches to implement all-optical flip-flops, working with a synchronization signal, will be presented and compared. In this type of optical bistable devices, the information present at the inputs produces effects on the outputs, throughout all the clock pulse period. The performance of optical clocked flip-flops will be studied in terms of extinction ratio (ER), switching energies an...
All-Optical Clocked D Flip-Flop Memory Using A Hybrid Integrated S-R Latch
Reis, Cláudia; Maziotis, A.; Kouloumentas, C.; Stamatiadis, C.; Bougioukos, M.; Calabretta, N.; Andre, Paulo; Dionisio, R.; Neto, B.; Dorren, H. J. S.We demonstrate, by using multiple Mach-Zehnder interferometer (MZI)-semiconductor optical amplifier structures, an all-optical synchronous D type flip-flop, with high-photonic integration capability. Experimental performance analysis shows its functional and performance feasibility and high-switching speeds were achieved. (C) 2011 Wiley Periodicals, Inc.

Experimental evaluation of all-optical asynchronous and synchronous memories
Reis, Cláudia; Maziotis, A.; Kouloumentas, C.; Stamatiadis, C.; Bougioukos, M.; Calabretta, N.; André, P.S.; Dionísio, Rogério Pais; Neto, BertaWe experimentally demonstrate the accuracy of an all-optical S-R latch and an optical S-R flip-flop based on hybrid integrated Mach-Zehnder Interferometers, with Semiconductor Optical Amplifier in each arm (MZI-SOA). The performance of both bistable devices will be studied and compared in terms of extinction ratio and switching times.
All-optical synchronous S-R flip-flop based on active interferometric devices
Reis, C.; Maziotis, A.; Kouloumentas, Ch.; Stamatiadis, C.; Bougioukos, M.; Calabretta, N.; André, Paulo; Dionisio, R.; Neto, B.; Dorren, H. J. S.An all-optical clocked set-reset flip-flop is experimentally demonstrated. It is based on a hybrid-integrated S-R latch and two additional Mach-Zehnder interferometer structures with semiconductor optical amplifiers acting as AND logic gates. The switching behaviour of the synchronous S-R flip-flop was investigated and 18 dB extinction ratio performance was achieved.
