Abstract

Una guía de ondas de fibra optica, una seccion de longitud (Lgr) que está modulada en índice de refraccion a fin de formar una retícula con unapluralidad de canales de longitud de onda de reflexion característicos, tiene una modulacion del índicede refraccion que coprende una modulacion de laamplitud con un componente subyacente de frecuencia mayor que define la forma del perfil de reflexion de cada uno de los canales de longitud de onda y,superpuesto sobre el mismo, un componente de frecuencia de menor período P que impone curvas envolventes repetidas sobre el componente de frecuencia mayor yque define la separacion de los canales de longitud de onda. En una forma de realizacion, el componente de frecuencia menor tiene la formade una funcionsinc con un índice de refraccion variable (delta n) y con desplazamiento de fase pi discretos (delta fi) cada curva envolvente para formar una retículasinc-muestrada. Así, puden proporcionarse retículas de fibra optica multicanal con chirp para la compensacion de la dispersion en enlaces de transmision delargo alcance.
