Abstract

FIBRA óTICA DE MODO SIMPLES Fibra ótica de modo simples incluindo um primeiro núcleo (300) apresentando um índice de refração (n~ 1~) constante dentro de um raio (a~ 1~) pré-determinado a partir do centro de uma fibra ótica, um segundo núcleo (302) que reveste o primeiro núcleo (300) e apresenta um índice de refração (n~ 2~) que diminui a partir do índice de refração (n~ 1~) do primeiro núcleo (300) com um aumento no seu raio, e um blindado (304) que reveste o segundo núcleo (302) e apresenta um índice de refração (n~ 0~) menor do que o índice de refração mínimo do segundo núcleo (302). Consequentemente, a estrutura do núcleo de uma fibra ótica é controlada, e a fibra ótica apresenta uma distribuição complexa do índice de refração de um tipo em degrau apresentando baixa dispersão e de um tipo triangular apresentando baixa perda, fabricando-se assim uma fibra ótica apresentando baixa dispersão e baixa perda.
