Abstract

EL SELECTOR COMPRENDE UN ACOPLADOR OPTICO (1) QUE TIENE UNA PRIMERA ENTRADA (2) PARA UNA SEÑAL DE ENTRADA OPTICA, UNA SEGUNDA ENTRADA (3) PARA UNA SEÑAL DE CONTROL OPTICA Y UNA SALIDA (4) PARA UNA SEÑAL COMBINADA, Y UNA CAVIDAD DE RESONANCIA (5) POR DETRAS DE LA SALIDA DEL ACOPLADOR (1) Y DESTINADA PARA RECIBIR LA SEÑAL COMBINADA. LA CAVIDAD DE RESONANCIA (5) CONTIENE UN MATERIAL OPTICAMENTE NO LINEAL, DE TAL FORMA QUE LOS CAMBIOS EN LA POTENCIA DE LA SEÑAL DE CONTROL OPTICO RESULTAN EN CAMBIOS EN LA FRECUENCIA DE RESONANCIA DE LA CAVIDAD (5). DURANTE SU USO, LA POTENCIA DE LA SEÑAL DE CONTROL OPTICO CONTROLA LA TRANSMISION O SUPRESION DE LA SEÑAL DE ENTRADA OPTICA A TRAVES DE LA CAVIDAD OPTICA. UN SELECTOR ACTUA COMO UN INTERRUPTOR SIMPLE O PARA SELECCIONAR UNA DE ENTRE UN NUMERO DE SEÑALES OPTICAS DE DIFERENTE LONGITUD DE ONDA. PREFERIBLEMENTE EL MATERIAL OPTICO ES ACTIVO Y LA CAVIDAD OPTICA (5) ESTA FORMADA POR UN AMPLIFICADOR LASER SEMICONDUCTOR.
