Abstract
Patente de Invenção para <B>"ESTOQUE DE ALIMENTAçãO DE CLORETO DE GERMANIO E SILOXANO PARA FORMAçãO DE VIDRO DE SìLICA E PROCESSO"<D>. é revelado um processo de fabricação de uma pré-forma de guia de onda ótica e guias de onda óticas que podem ser estiradas em uma fibra. Um estoque de alimentação que inclui uma mistura de siloxano e cloreto de germânio e um aparelho de manufaturamento de pré-forma de guia de onda ótica é também revelado. A revelação inclui adicionalmente a mistura antes de deposiçào e uso de silixano de alta pureza com cloreto de germânio de alta pureza para produzir sílica dopada com germânio. As linhas de distribuição para o estoque de alimentação no lado de deposição podem ser aquecidas a 175°C a 200°C.
