Abstract

UN SISTEMA DE REDUCCION DE BLOQUEO DONDE UNA RED EQUIVALENTE DE PERFECTO AZAR, QUE TIENE UNA PLURALIDAD DE ETAPAS DE NODOS SUCESIVAMENTE INTERCONECTADAS POR ETAPAS DE ENLACES, ESTA VENTAJOSAMENTE COMBINADA CON EXPANSION ANTES DE QUE LAS ETAPAS DE NODOS Y/O CONCENTRACION, DESPUES DE LAS ETAPAS DE NODOS, EN UNA MANERA QUE PERMITE EL DISEÑO DE UN SISTEMA CON PROBABILIDAD ARBITRARIA DE BLOQUEO BAJO O CERO. UNA EJECUCION DEL SISTEMA FOTONICO ILUSTRATIVO UTILIZA APARATO OPTICO DE ESPACIO LIBRE PARA EFECTUAR UNA INTERCONEXION DE CRUZAMIENTO, DE ESCASAS PERDIDAS, DE DOS CONJUNTOS DE NODOS DE CONMUTACION, COMPRENDIENDO, POR EJEMPLO, DISPOSITIVOS (S-SEED) SIMETRICOS DE EFECTO AUTOELECTROOPTICO. SE UTILIZAN VARIAS TECNICAS DE COMBINACION DE HACES DE ESCASAS PERDIDAS PARA DIRIGIR CONJUNTOS MULTIPLES DE HACES A UN CONJUNTO DE S-SEED, Y REDIRIGIR UN CONJUNTO DE HACES DE SALIDA REFLEJADOS A UNA ETAPA DE NODO POSTERIOR.
