Abstract

FIBRAS ÓPTICAS DE SÍLICA ESTRUTURADAS E REVESTIDAS POR SÍLICA. É descrito um novo tipo de fibra óptica totalmente em sílica; uma fibra óptica de sílica estruturadas e revestidas por sílica (SSCS), cujo revestimento é estruturado para fornecer mistura de modos dentro do núcleo; e/ou ter um índice de refração efetivo médio. Sua seção transversal é essencialmente simétrica, pode ser usada, entre outros objetos, para fornecer saídas mais planas e livres de manchas a partir de lasers de fibra ou outras fontes fotônicas de modo limitado. Construir a nova estrutura de fibra em torno de um núcleo de laser dopado com terras raras fornece um melhor laser/amplificador de fibra para bombeamento de revestimento. O revestimento de sílica estruturada contém camadas pareadas, nas quais uma camada de sílica descendente é seguida por uma camada de sílica pura, ou menos descendente, ou mesmo sílica ascendente, e o número de camadas pareadas é, tipicamente, de 5 a 25, e, em geral, dentro das camadas pareadas a razão de espessura da camada de IR superior de silicato a sílica descendente é muito ampla, situando-se entre 0,0625 a 16, dependendo do uso pretendido das fibras SSCS. Em algumas versões, o material do núcleo principal pode ser sílica ascendente com sílica pura ou sílica descendente como o segundo componente primário.
