Abstract

La invención comprende un núcleo (10); un involucro óptico (20) alrededor del núcleo y una región definida por al menos una porción intermediaria aliviadora de tensión (30) dispuesta entre núcleo e involucro. Cada porción presenta un índice de difracción, denominados respectivamente n1, n2 y n3, cuyo valor varía, de manera de proveer aumento en el largo de onda de corte; un coeficiente de dilatación térmica y una viscosidad adecuados para reducir los niveles de tensión interna al menos en el núcleo hasta valores que permitan la obtención de atenuación y dispersión cromática aceptables para una región de largo de onda.
