Abstract
Las modalidades de la presente invención proporcionan un divisor, una red de distribución óptica, y un método para determinar una longitud de onda. El divisor incluye una sección óptica de entrada, N secciones de ramificación óptica, y al menos (N–1) estructuras de filtro óptico. Cada estructura de filtro óptico refleja una señal óptica de una longitud de onda. Las al menos (N–1) estructuras de filtros ópticos incluyen una estructura de filtro óptico especial y las al menos (N–3) estructuras de filtros ópticos comunes, y una longitud de onda de una señal óptica reflejada por cada una de las al menos (N–3) estructuras de filtros ópticos comunes es una longitud de onda común. Una longitud de onda de una señal óptica reflejada por una primera estructura de filtro óptico especial es una primera longitud de onda especial, y una longitud de onda de una señal óptica reflejada por una segunda estructura de filtro óptico especial es una segunda longitud de onda especial. Al menos (N–3) longitudes de onda comunes constituyen una secuencia aritmética, una diferencia entre la primera longitud de onda especial y una longitud de onda común más grande es mayor que una tolerancia de la secuencia aritmética, y una diferencia entre la segunda longitud de onda especial y una longitud de onda común más pequeña es mayor que la tolerancia de la sucesión aritmética. Esto reduce los recursos de longitud de onda.
