Abstract

UN SISTEMA DE TRANSMISION OPTICA INCLUYE: UN INTERFEROMETRO (2) Y UNA FUENTE DE SEÑALES OPTICAS (24). EL INTERFEROMETRO (2) COMPRENDE UN ACOPLADOR OPTICO DE CUATRO PUERTOS (4) QUE TIENE UN PRIMERO Y UN SEGUNDO PUERTO DE ENTRADA (6 Y 8) Y UN PRIMERO Y UN SEGUNDO PUERTO DE SALIDA (10 Y 12), UNA FIBRA OPTICA DE SILICE (14) QUE ACOPLA EL PRIMERO Y EL SEGUNDO PUERTO DE SALIDA (10 Y 12) QUE EXHIBE LA NO LINEALIDAD DE LA OPTICA KERR Y UN AMPLIFICAR DE FIBRA DE ERBIO (18) SITUADO ASIMETRICAMENTE ENTRE LOS PUERTOS DE SALIDA (10 Y 12). LA FUENTE DE SEÑALES OPTICAS (24) ESTA ACOPLADA CON EL PRIMER PUERTO DE ENTRADA (6) DEL INTERFEROMETRO (2). EL SISTEMA ES OPERADO EN UN REGIMEN EN EL QUE LAS SEÑALES OPTICAS SATURAN EL AMPLIFICADOR (18) SUPRIMIENDO DE ESTA FORMA CUALQUIER SALIDA OSCILATORIA, Y SU POTENCIA ES SUFICIENTE PARA CONMUTAR UNA SEÑAL DE ENTRADA ACOPLADA AL PRIMER PUERTO DE ENTRADA (6) CON EL SEGUNDO PUERTO DE ENTRADA (8). ESTO SUMINISTRA UNA CONFORMACION DE IMPULSOS Y UNAS CARACTERISTICAS DE AMPLIFICACION QUE SON RELATIVAMENTE INSENSIBLES A LA POTENCIA DE ENTRADA DE LAS SEÑALES OPTICAS DESDE LA FUENTE OPTICA (24).
