Abstract

DISPOSITIVO OPTICO QUE CONSTA DE UNA PRIMERA Y UNA SEGUNDA GUIA DE ONDAS OPTICAS (1,2) CONECTADAS ENTRE LAS RESPECTIVAS COMPUERTAS DE SALIDA Y ENTRADA DE UN PRIMER Y UN SEGUNDO ACOPLADOR OPTICO (3,4). EL PRIMER ACOPLADOR CONSTA DE AL MENOS UNA COMPUERTA DE ENTRADA Y ESTA DISEÑADO PARA ACOPLAR LAS SEÑALES OPTICAS RECIBIDAS EN LA COMPUERTA DE ENTRADA A SUS COMPUERTAS DE SALIDA SEGUN UNA RELACION DE ACOPLAMIENTO PREDETERMINADA. EL SEGUNDO ACOPLADOR TIENE, AL MENOS, UNA COMPUERTA DE SALIDA, Y ACOPLA LAS SEÑALES OPTICAS RECIBIDAS EN CADA COMPUERTA DE ENTRADA (7,8) A SU COMPUERTA DE SALIDA SEGUN UNA RELACION DE ACOPLAMIENTO PREDETERMINADA. LA PRIMERA Y SEGUNDA GUIAS DE ONDAS (1,2) ESTAN HECHAS DE MATERIALES QUE PRODUCEN EFECTOS SOLITON CUANDO SE INTRODUCEN IMPULSOS OPTICOS, A INTENSIDADES DE FUNCIONAMIENTO, EN LAS GUIAS DE ONDAS, DE MANERA QUE LA PROPAGACION DEL IMPULSO DEPENDE DE LA DISPERSION Y LAS PARTES DE UN IMPULSO OPTICO RECIBIDO EN LA ENTRADA DEL PRIMER ACOPLADOR (3) SON ACOPLADAS PORESTE EN LAS GUIAS DE ONDAS (1,2) Y LLEGAN SINCRONICAMENTE, PERO DESPLAZADAS EN FASE ENTRE SI, AL SEGUNDO ACOPLADOR (4) TRAS RECORRER LAS GUIAS DE ONDAS. EL DISPOSITIVO PUEDE TAMBIEN CONFIGURARSE PARA QUE PROPORCIONE CONMUTACION OPTICA Y FUNCIONES LOGICAS.
