Abstract
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
