Abstract

"EQUIPAMENTO E PROCESSO PARA FABRICAçãO DE GRADE óPTICA". Equipamento de fabricar grade óptica compreende uma máscara de fase (40) para dividir um feixe de luz incidente (30)em uma pluralidade de feixes difratados; e um arranjo de focalizar (60) para receber a luz da máscara de fase de convergir pelo menos dois feixes difratados juntos de ordem não-zero, de modo a gerar uma região de interferência entre os feixes convergidos, de modo que uma estrutura de grade possa ser impressa sobre uma guia de onda óptica (80) colocada na região de interferência; a máscara de fase e pelo menos uma parte do arranjo de focalizar sendo móveis uma em relação a outra de modo a alterar o ângulo de convergência dos feixes convergidos.
