Abstract

"FIBRA DE INCLINAçãO DE DISPERSãO BAIXA DE DISPERSãO POSITIVA". é revelado uma guia de onda ótica de modo simples, tendo um núcleo segmentado de pelo menos dois segmentos. O índice de refração relativo, o perfil de índice e as dimensões radiais do segmento de núcleo são selecionados para proporcionar uma fibra de guia de onda ótica tendo propriedades adequadas para um sistema de telecomunicação de alta performance que opera na janela de comprimento de onda de cerca de 1530 nm a 1570 nm. Concretizações da invenção apresentando dois, três e quatro segmentos são descritas. Para eliminar os efeitos não-lineares, tais como FWM e SPM, que ocorrem em sistemas de alta taxa, de alta performance, a área efetiva da guia de onda é produzida para ser maior do que cerca de 60 <109>m^ 2^, mais preferivelmente maior do que 65 <109>m^ 2^, e mais preferivelmente maior do que 70 <109>m^ 2^. A dispersão total é preferivelmente positiva e igual a pelo menos 2 ps/nm-km em 1530 nm. Esta dispersão total junto com uma inclinação de dispersão total menor do que 0,1 ps/nm^ 2^-km assegura um efeito de FWM mínimo sobre a janela de comprimento de onda.
