Abstract

UN APARATO DE CONMUTACION OPTICA COMPRENDE DOS GUIAS DE ONDA 3 Y 4 OPTICAS FORMADAS POR DIFUSION DE TITANIO DENTRO DE UN CUERPO DE LITIO NIOBIO. UNOS ELECTRODOS PLANOS 7 Y 8 ESTAN PEGADOS A LA SUPERFICIE DEL CUERPO 2 DISPUESTO DE FORMA QUE UN CAMPO ELECTRICO PUEDE SER APLICADO A TRAVES DEL CUERPO. ESTO PERMITE QUE LA DISTANCIA ENTRE LAS GUIAS DE ONDA 3 Y 4 SEAN CAMBIADAS EN FUNCION DEL CAMPO APLICADO Y EN CONSECUENCIA PRODUCE UN CAMBIO EN LA CONSTANTE DE ACOPLAMIENTO DE LAS GUIAS DE ONDA 7 Y 8, DE ESTE MODO LA RESPUESTA DE CONMUTACION DEL CONMUTADOR PUEDE SER POTENCIADA.
