Abstract

"FIBRA E SISTEMA DE TRANSMISSãO óPTICA, E, MéTODO PARA CONTROLAR EFEITOS NãO-LINEARES EM TRANSMISSãO DE FIBRA óPTICA". Uma fibra de transmissão óptica, tendo um perfil de índice de refração com uma área de índice de refração aumentando no núcleo interno da fibra, uma região anular posicionada radialmente fora do núcleo interno, com um índice de refração excedendo o índice do núcleo interno e pelo menos um região de baixo teor de dopante em uma região de seção transversal entre o núcleo interno e a região anular. Uma camada
