Abstract

Novel all-optical implementations for logic AND and XOR gates are experimentally demonstrated at 2.5Gb/s based on cavity-enhanced four-wave-mixing (CE-FWM) combined with optical injection locking phenomena in monolithically integrated semiconductor ring lasers (SRLs). All-optical AND gate with simultaneous wavelength conversion have been achieved using the CE-FWM. XOR function is demonstrated using two parallel SRLs, each performing one part of XOR Boolean equation. Error-free operation with extinction ratio higher than 10dB confirms the suitability of SRLs for all-optical logic applications.
