Abstract

UN MODULADOR ELECTRO-OPTICO (10) INCLUYE UN PAR DE CANALES OPTICOS GUIA-ONDAS (20, 22) FORMADOS EN UN SUBSTRATO NIOBATO DE LITIO (12) Y UNA GUIA-ONDAS COPLANAR DE RF SUPERPUESTA (36). UNA ESTRUCTURA DE ELECTRODOS PERIODICA (48) DEL TIPO DE INTERACCION INTERMITENTE EMPLEA UNA PLURALIDAD DE TETONES MEDIANOS (52) PARA MANTENER LA FASE DE LA FRECUENCIA DE CONDUCCION RF EN FASE CON LA SEÑAL OPTICA. EL MODULADOR (10) TAMBIEN UTILIZA TETONES CORTOS (64) Y ORIFICIOS DE ENTRADA (42) Y DE SALIDA (44) DE VARIACION PROGRESIVA (42) PARA EMPAREJAR Y TRANSFORMAR IMPEDANCIAS.
