Abstract
SE DESCRIBE UN SISTEMA DE PROCESAMIENTO OPTICO COMPLETO PARA CONVERTIR E INTERCONECTAR SEÑALES OPTICAS DE UNA FORMA MULTIPLEXADA DE DIVISION DE LONGITUD DE ONDA (WDM) A UNA FORMA OPTICA MULTIPLEXADA DE DIVISION DE TIEMPO (OTDM), EN DONDE LA SEÑAL WDM INICIAL COMPRENDE TIPICAMENTE UN FORMATO DE SEÑALIZACION DE NO RETORNO A CERO (NRZ). EL SISTEMA COMPRENDE UNA PLURALIDAD DE DATOS NRZ MODULADOS, CANALES WDM OPTICOS CW (W, X, Y, Z) QUE SE MODULAN POR FASE CRUZADA, Y DE ESTA FORMA SE ENSANCHAN ESPECTRALMENTE, EN UN ELEMENTO OPTICO NO LINEAL (745), MEDIANTE UNA SEÑAL DE IMPULSO DE RELOJ PRONUNCIADA. LA SEÑAL RESULTANTE COMPRENDE UNA REPRESENTACION (RZ) DE LA SEÑAL ORIGINAL NRZ. LA SEÑAL RZ SE DESPLAZA TEMPORALMENTE MEDIANTE UN ELEMENTO DISPERSIVO (760), QUE DESPLAZA TEMPORALMENTE CADA CANAL DE LONGITUD DE ONDA EN UNA CANTIDAD PREDETERMINADA, PARA PRODUCIR UNA SEÑAL OTDM INTERCALADA POR LONGITUD DE ONDA. LA SEÑAL SE CONVIERTE ENTONCES EN LONGITUD DE ONDA MEDIANTE MODULACION DE FASE CRUZADA CON RAYO DE CONTROL CW EN UN SEGUNDO ELEMENTO OPTICO NO LINEAL (760), PARA SUMINISTRAR UNA SEÑAL OTDM DE LONGITUD DE ONDA SIMPLE.
