Abstract
UN MULTIPLEXOR/DEMULTIPLEXOR DE LONGITUD DE ONDA EFICAZ INCLUYE UNA PLURALIDAD DE ACOPLADORES OPTICOS DE 2X2 (122,180,200,220), CADA UNO TIENE UN PAR DE REJILLAS ADAPTADAS (130,142; 182,184; 202,204; Y 222,224), QUE TIENEN LONGITUDES DE ONDA DE PASO BANDA ({LA}{SUB,1},{LA}{SUB,2},{LA}{SUB,3},{LA}{SUB,4}), RESPECTIVAMENTE, UNIDAS A DOS DE LOS PUERTOS. UNA SEÑAL DE ENTRADA (116) SE INTRODUCE EN UN PUERTO (120) Y ES DIVIDIDA Y REFLEJADA FUERA DE LAS REJILLAS (130,142) Y DESPUES RECOMBINADA PARA SUMINISTRAR TODA LA SEÑAL DE ENTRADA (116) EN UN PUERTO DE SALIDA (150) Y NINGUNA REFLEXION FUERA DEL PUERTO (120). OTRA SEÑAL DE ENTRADA (154) ES INCIDENTE SOBRE LA REJILLA (142) QUE ES PASADA POR LA REJILLA (142) Y ES ACOPLADA SOBRE EL PUERTO DE SALIDA (150) CON LA SEÑAL (116) COMO UNA SEÑAL (160). UNA ORDENACION SIMILAR EXISTE PARA LOS OTROS ACOPLADORES (180,200,220) CONECTADOS EN SERIE, CADA UNO DE LOS CUALES AÑADE OTRA LONGITUD DE ONDA DE ENTRADA. ALTERNATIVAMENTE, EN UNA APLICACION DE DESMULTIPLEXACION LA SEÑAL (116) PUEDE SER DE BANDA ANCHA Y LAS SEÑALES (154,190,206,2309) SERIAN LONGITUDES DE ONDA DE SALIDA SEPARADAS.
