Acesso em:.https://repositorio.ufpa.br/handle/2011/10275In this work, proposes all-optical logic gates device structure based on a Michelson interferometer (MI) composed of semiconductor optical amplifier (SOA) forming a structure of SOA-MI logic devices with symmetrically identical Fiber Bragg Grating (FBG) at the output of each of its arms, for numerical simulation of the all-optical AND, OR and NOR logic gates of two binary input signals with different bit numbers using the cross-gain modulation (XGM) technique at 10 Gb/s bit rate and filter bandwidth at 10, 20 and 40 GHz using OptiSystem 15.0 software by OptiWave Corporation, to demonstrate and extract simple design rules for high-speed optical processing and analysis of non-linear SOA-induced properties. In addition, this work includes the study of the effect of bandwidth and number of bits on received power, minimum bit error rate (BER), maximum quality factor (Q-factor), Optical Signal to Noise Ratio (OSNR) and optical spectrum, which demonstrates high-speed gates and performance. Were run the SOA-MI-based logic gates with some parameters and the results can demonstrate a structure of high-performance optical logic devices with high speed.Acesso AbertoTotalmente ópticasPortas lógicasInterferômetro de MichelsonAmplificador Óptico SemicondutorFator de qualidadeTaxa de erro de bitsAll-opticalLogic gateMichelson interferometerSemiconductor Optical Amplifier (SOA)Quality factorBit error gatePortas lógicas totalmente ópticas baseado em interferômetro de Michelson com amplificador óptico semicondutorTotally optical logic doors based on Michelson interferometer with semiconductor optical amplifierDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::MEDIDAS ELETRICAS, MAGNETICAS E ELETRONICAS INSTRUMENTACAO::SISTEMAS ELETRONICOS DE MEDIDA E DE CONTROLEELETROMAGNETISMO APLICADOTELECOMUNICAÇÕES
