Abstract

Se dispersan señales opticas de acuerdo a su longitud de onda mediante un generador de diferencia de longitud de trayecto optico que acopla una trayectoria individual que transmite una pluralidad de diferentes señales de longitud de onda a trayectorias multiples, transmitiendo por separado las diferentes señales de longitud de onda; el generador de longitud de trayecto optico puede formarse mediante una pila reflectora que tiene una pluralidad de superficies parcialmente reflectora para reflejar porciones sucesivas de la energía de cada una de las diferentes señales de longitud de onda a lo largo de trayectos opticos de diferente longitud.
