Abstract

SISTEMA ÓPTICO COMPREENDENDO UM DISPOSITIVO RECONFIGURÁVEL E MÉTODO DE CONTROLE DO SISTEMA ÓPTICO. A presente invenção fornece um sistema óptico (100) incluindo: um dispositivo óptico reconfigurável (103) com multiplexação por divisão de comprimento de onda, compreendendo uma pluralidade de atuadores (A1-AN) e tendo associado um número de canais ópticos (M) e um número de graus de liberdade (N) inferior ao número de canais ópticos; uma fonte de estímulo óptico (106) conectada no dito dispositivo óptico reconfigurável (103) para prover um sinal de estímulo óptico (Sin) tendo uma banda de comprimento de onda incluindo uma pluralidade de comprimentos de onda associados com os canais ópticos; um dispositivo de conversão óptico-elétrico (200) configurado para receber a partir do dito dispositivo óptico reconfigurável (103) um sinal de monitoramento óptico (Sout) correspondente ao sinal de estímulo óptico (Sin) e para prover um grupo de sinais elétricos de intensidade (SEL1-SELK), cada qual representativo de uma intensidade do sinal de monitoramento óptico (Sout) avaliada em um comprimento de onda relativo incluído na dita banda. O sistema também inclui um dispositivo de controle (110) configurado para controlar a pluralidade de atuadores (A1-AN) de acordo com o dito grupo de sinais elétricos (SEL1-SELK) e de acordo com uma lei de controle.
