Abstract

PRÉ-MOLDES PARA FIBRAS ÓPTICAS DE SAÍDA LIVRES DE MANCHAS TENDO SEÇÕES DE SÍLICA ESTRUTURADAS, MÉTODOS PARA FABRICAR REFERIDOS PRÉ-MOLDES E FIBRAS ÓPTICAS DE SAÍDA APRIMORADAS LIVRES DE MANCHAS. São apresentados a produção e o novo tipo de pré-moldes que produzem, mediante desenho, nova classe de fibras ópticas, fibras ópticas de saída aprimoradas e livres de manchas. Fibras úteis, fornecendo saída suave livre de manchas com transmissão de luz de topo plano a partir de fontes gaussianas ou de poucas fontes de modos são produzidas a partir de pré-moldes introduzidos nas mesmas. É apresentada ainda a produção exclusiva desses pré-moldes aprimorados. Os pré-moldes e, portanto, as fibras produzidas em dimensões de núcleo variáveis de 100µm a mais de 1000µm, são baseadas em uma seção de sílica estruturada de área de mistura de modo adjacente ao núcleo interno, ou no caso de núcleo não circular, dentro do núcleo. O processo de Deposição de Vapor de Plasma é modificado para obter seções estruturadas de maneira bem controlada. As seções estruturadas são compostas por um número de pares de camadas, onde uma camada fina descendente é alternada com uma camada de material de núcleo muito mais espessa. A razão entre a espessura da camada de núcleo e a espessura da camada descendente é de 3 a 25. O número de camadas emparelhadas é tipicamente de 8 a 30 pares de camadas. O NA efetivo da seção estruturada depende das particularidades da seção de sílica estruturada e da camada individual descendente. Ambos os exemplos de núcleo interno circular e de núcleo não circular são possíveis e são discutidos aqui.
