Abstract

Un modulador optico incluye un guiaondas optico y una estructura de electrodo acoplada con el guiaondas de manera tal que una senal moduladora aplicada ala estructura de electrodo varía el índice de refraccion del guiaondas a fin de producir una senal de salida optica modulada. El electrodo se fabrica en formade una línea de transmision cerrada en un cortocicuito. La relacion entre la longitud de onda de la senal moduladora y la longitud efectiva del electrodo estácomprendida entre 2,1 y 4,0 y de preferencia es de aproximadamente 2,7. El modulador puede construirse para que provea modulacion de fase o bien de amplitud.También se provee un método de transmision optica con supresion de SBS y un sistema moduladr optico.
