Abstract

resumo “método para a produção de fibra óptica tendo perturbações de índice controladas” um método à produção de uma fibra óptica é fornecido. o método inclui as etapas de desenho de uma fibra óptica a partir de uma fonte de vidro aquecida em um forno e introdução de perturbações de índice à fibra óptica por meio de uma pluralidade de fontes de perturbação arranjadas numa pluralidade de locais azimutais diferentes. as perturbações de índice são introduzidas de forma síncrona em diferentes locais ao longo do comprimento axial da fibra por uma pluralidade de fontes de perturbação num padrão geralmente helicoidal na superfície externa da fibra numa forma de realização. de acordo com uma outra forma de realização, as perturbações de índice são introduzidas por uma pluralidade de fontes de perturbação em diferentes frequências.
