Abstract

"PROCESSO PARA FABRICAçãO DE UM GRADEAMENTO DE FIBRA óPTICA CHILREADO, GRADEAMENTO DE FIBRA óTICA, SISTEMA DE FONTE óPTICA". Um processo de fabricação de um gradeamento de fibra óptica chilreado, de modo que o gradeamento tenha uma resposta dependente do comprimento de onda desejada predeterminada através de uma largura de faixa operacional compreende a apodização do gradeamento de modo que um grau de apodização em uma posição longitudinal ao longo do gradeamento corresponda à resposta desejada no comprimento de onda óptico refletido nessa posição longitudinal ao longo do gradeamento.
