Abstract
UN DISPOSITIVO DE CONMUTACION OPTICO INTEGRADO PARA CONVERTIR DE FORMA CONMUTABLE UNA FRACCION DE UNA PRIMERA SEÑAL EN MODO GUIADO EN UN SEGUNDA SEÑAL EN MODO GUIADO DE RANGO DIFERENTE. AÑADIDOS A UN CONVERSOR EN MODO PASIVO (C) QUE TIENE UNA GUIA DE ONDA BIMODAL, EN QUE DICHA CONVERSION PUEDE TENER LUGAR MEDIANTE UN ACOPLAMIENTO PERIODICO DE LAS SUPERFICIES DE ACOPLAMIENTO 1-N COMO RESULTADO DE UNA GEOMETRIA ESPECIFICA (F, G), HAY UNOS ELEMENTOS (10, 14) PARA ROMPER DE FORMA CONMUTABLE EL ACOPLAMIENTO, CUYO RESULTADO ES QUE LA CONVERSION TIENE O NO TIENE LUGAR. PREFERENTEMENTE, EL DISPOSITIVO ESTA HECHO DE UN MATERIAL SEMICONDUCTOR Y LA MODIFICACION SE LLEVA A CABO MEDIANTE LA INYECCION DE UNA PORTADORA DE CARGA. SE DESCRIBEN CONMUTADORES DE ACTIVACION/DESACTIVACION Y DIRECCIONALES BASADOS EN ESTO. VENTAJAS: UNA BUENA INTEGRABILIDAD, POCA LONGITUD, NO EXISTEN PARAMETROS CRITICOS EN LA FABRICACION Y FUNCIONAMIENTO A BAJAS CORRIENTES DE CONTROL.
