Abstract
An optical fiber having an axial direction and a cross section perpendicular to the axial direction, the optical fiber having a first light guiding fiber portion with a cladding region with a plurality of spaced apart cladding voids extending longitudinally in the fiber axial direction and a core region bounded by the cladding region, and a solid light transparent fiber portion having a first end facing the first light guiding fiber portion and a second end forming an end face of the optical fiber. The solid light transparent fiber portion provides a hermetic sealing of the cladding voids of the first light guiding fiber portion. A method of producing such an optical fiber and its use, such as an optical fiber connector and an article having a microstructured optical fiber with hermetically sealed end face, are also included.
