J.Izquierdo,D.Garces,I.Integrated multi-bit all-optical NOR gate for high speed data processingART-2013-81266In this paper, we study the use of integrated semiconductor optical amplifiers as the basic building block for larger-scale programmable photonic circuits. Making use of the non-linear response of these devices, we study the performance of 4-bit all-optical NOR gates based on fully integrable components for high speed all-optical look up tables. Feasibility of the proposed architecture is demonstrated by proof-of-concept experiments using both commercially available devices and photonic integrated circuits.2013http://zaguan.unizar.es/record/14777210.1109/JLT.2013.2245099http://zaguan.unizar.es/record/147772oai:zaguan.unizar.es:147772info:eu-repo/grantAgreement/ES/MICINN/TEC2010-19418Journal of Lightwave Technology 31, 8 (2013), 1178-1184All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
