Abstract
Guías de ondas ópticas que tienen núcleos con perfiles de índices graduados radialmente y éstas manifiestan una dispersión de impulsos importantemente reducida, que resulta de diferencias de velocidades de grupo entre modos. Este efecto reductor de la dispersión emplea un perfil de índice continuo, graduado radialmente, desde un valor máximo en el centro del núcleo hasta un valor mínimo junto a la superficie de contacto entre núcleo y revestimiento.
