Abstract

SE DESCRIBE UN ACOPLADOR DE FIBRAS OPTICAS FUNDIDAS EN EL QUE UNA DE LAS FIBRAS TIENE UNA CONSTANTE DE PROPAGACION QUE, EN LA ZONA DE ACOPLAMIENTO, ES LIGERAMENTE DIFERENTE DE LA QUE POSEE LA OTRA. LA DIFERENCIA DE CONSTANTES DE PROPAGACION SE PUEDE DISPONER DE MODO QUE PROPORCIONE RELACIONES DE DIVISION SELECCIONADAS EN UN INTERVALO RELATIVAMENTE AMPLIO DE LONGITUDES DE ONDA. SE DESCRIBE TAMBIEN UN METODO PARA FORMAR DICHO ACOPLADOR RETORCIENDO CONJUNTAMENTE DOS FIBRAS Y LANZANDO RADIACION OPTICA A UNA O AMBAS FIBRAS. EL INVENTO ES APLICABLE A REDES DE COMUNICACIONES.
