A photonic crystal fiber (1) and a method of manufacturing the crystal fiber, the photonic crystal fiber comprising a fiber body having a core (2) and a clad (3) with a plurality of fine holes (3a) provided so as to surround the core (2) and extending along the core (2); the method of manufacturing the crystal fiber comprising the steps of closing the openings of the fine holes (3a) in a clad (3) at the fiber end part of the fiber body, by a closing material (5) with a refractive index lower than that of the core (2) and polishing the end faces of the fibers.
L'invention concerne une fibre de cristal photonique (1) et son procédé de fabrication, la fibre de cristal photonique comprenant un corps de fibre ayant un noyau (2) et une gaine (3) présentant une pluralité d'orifices minces (3a) disposés de manière à entourer le noyau? ¿(2) et s'étendant le long du noyau (2). Le procédé de fabrication de la fibre de cristal consiste à fermer les ouvertures des orifices minces (3a) dans une gaine (3) au niveau de la partie d'extrémité de la fibre du corps de fibre à l'aide d'une substance de fermeture (5) ayant un indice de réfraction inférieur à celui du noyau (2) et à polir les faces d'extrémité des fibres.
