Abstract

Se presenta la producción y un nuevo tipo de preformas que dan lugar, tras el estirado, a una nueva clase de fibras ópticas, fibras ópticas de salida libre de manchas de luz brillantes (speckles) mejoradas; las fibras útiles, que proporcionan una salida llana y libre de manchas de luz brillantes (speckles) con una transmisión superior plana de la luz procedente de fuentes gaussianas o de pocos modos, se producen a partir de las preformas introducidas en el presente documento; también se presenta la producción única de estas preformas mejoradas; las preformas y, de esta manera, las fibras producidas en dimensiones de núcleo variables desde aproximadamente 100 µm hasta por encima de 1000 µm, se basan en una sección de sílice estructurada de área de mezcla de modos adyacente al núcleo interno, o en el caso de núcleo no circular, dentro del núcleo; el proceso de deposición en fase vapor por plasma se modifica para lograr las secciones estructuradas de forma bien controlada; las secciones estructuradas se componen de un número de pares de capas, donde se alterna una capa fina dopada hacia abajo con una capa de material de núcleo mucho más gruesa; la relación del grosor de la capa de núcleo con respecto al grosor de la capa dopada hacia abajo es de aproximadamente 3 a 25; el número de capas emparejadas es típicamente de entre aproximadamente 8 a 30 pares de capas; la NA efectiva de la sección estructurada depende de las particularidades de la sección de sílice estructurada y de la capa individual dopada hacia abajo; son posibles tanto los ejemplos de núcleo interno circular como los ejemplos de núcleo no circular, y se discuten en el presente documento.
