Abstract

DE ACUERDO CON LAS ENSEÑANZAS DE LA INVENCION, SE SUMINISTRA UN MODULADOR OPTO-ELECTRICO DE RENDIMIENTO MEJORADO (30 O 70) QUE COMPRENDE LOS DESAJUSTES DE VELOCIDAD DE FASE ENTRE LA MODULACION OPTICA Y UNA SEÑAL ELECTRICA DE RF. EL MODULADOR (30) COMPRENDE UNA GUIA DE ONDAS OPTICA (38, 40) FORMADA EN UN SUBSTRATO (32) Y ACOPLADA A UNA ENTRADA OPTICA (56). UNA GUIA DE ONDAS DE RF (46, 48) SE FORMA SOBRE EL SUBSTRATO (32) PARA APLICAR UN CAMPO ELECTRICO (59) A UNA REGION DE MODULACION (50) ADYACENTE A LA GUIA DE ONDAS OPTICA DE MANERA QUE SE MODULE UNA SEÑAL OPTICA. EL SUBSTRATO (32) TIENE UNA DOMINANTE FERROELECTRICA QUE INCLUYE REGIONES PERIODICAMENTE INVERTIDAS Y NO INVERTIDAS (54 Y 52) QUE COMPENSAN LAS DIFERENCIAS DE FASE DENTRO DE LA REGION DE MODULACION (52). EN UNA CONFORMACION REFERIDA, LA GUIA DE ONDAS OPTICA INCLUYE DOS GUIAS DE ONDAS OPTICAS SUBSTANCIALMENTE PARALELAS (38 Y 40) QUE TIENEN SALIDAS COMBINADAS PARA SUMINISTRAR UNA SEÑAL (60) DE SALIDA OPTICA MODULADA EN AMPLITUD (AM).
