Abstract

APARATO PARA OBTENER UN PEINE QUE TIENE UN GRAN NUMERO DE DIENTES OPTICOS, Y COMPRENDE UN BUCLE (3) OPTICO, QUE INCLUYE UN AMPLIFICADOR (5) OPTICO, UN CAMBIADOR (4) DE FRECUENCIAS Y UN FILTRO (6) OPTICO. UNA SEÑAL, PROCEDENTE DE UN LASER (9), SE ACOPLA PARCIALMENTE DENTRO DEL BUCLE MEDIANTE UN ACOPLADOR (7), EN TAL FORMA QUE UNA PARTE DE EL ES SALIDA EN EL PUERTO DE SALIDA (10). LA SEÑAL EN EL BUCLE (SEÑAL DE RETROALIMENTACION) SE AMPLIFICA POR EL AMPLIFICADOR (5) Y SE CAMBIA DE FRECUENCIA POR EL CAMBIADOR DE FRECUENCIAS (4), ACOPLANDOSE DESPUES PARCIALMENTE FUERA DEL BUCLE POR EL ACOPLADOR (7). LA PARTE ACOPLADA FUERA DEL BUCLE (LA SEÑAL DE SALIDA) SALE POR EL PUERTO 10 DE SALIDA. ESTE PROCEDIMIENTO SE REPITE PARA OBTENER EL NUMERO DESEADO DE SEÑALES DE SALIDA QUE SALEN POR EL PUERTO 20 DE SALIDA. LA SEÑAL PROCEDENTE DEL LASER (9) PUEDE SER CONTINUA O PULSATORIA.
