Abstract

Patente de Invenção para <B>"SENSIBILIDADE DIMINUìDA DE H~ 2~ EM FIBRA óTICA"<D>. é descrito um método de fabricação fibra de guia de onda ótica à hidrogênio. A pré-forma de fuligem é aquecida e imersa em um gás haleto de metal. Uma espécie de metal reduzida é então incorporada na fuligem de vidro antes da sinterização ou consolidação da pré-forma de fuligem. A banda absorção de hidrogênio ao redor de 1539 nm é substancialmente eliminada a partir das guias de onda feitas a partir da pré-forma tratada por um gás precursor.
