Abstract

Se describe un metodo y aparato para aplicaciones de telecomunicaciones, tales como conmutacion de multiplexion y desmultiplexion (Add/Drop); una fuente (70, 72, 74, 76) de senales opticas de entrada (10) se dirigen a un elemento optico difractivo movible o MDOE (12); cada una de las senales opticas es de una longitud de onda particular; el MDOE genera y distribuye senales opticas de salida (92, 94) entre estaciones de salida (88, 90).
