    摘要： A method of fabricating a hollow-core photonic-bandgap fiber, comprising the steps of: providing a stack of capillaries, wherein the stack has a hollow core and the capillaries at a boundary of the core comprise a plurality of first, corner core capillaries and a plurality of second, intermediate core capillaries; applying a pressure differential between the corner core capillaries and the intermediate core capillaries, whereby a size of the corner core capillaries can be controlled in relation to the intermediate core capillaries; and reducing the stack to a fiber, wherein the fiber has a hollow core and a cladding which surrounds the core at a core boundary and comprises a lattice or network of struts and interstitial nodes which together define an array of cavities.

    摘要： The invention relates to a preform and to a method for producing said preform for drawing a microstructured optical fiber, on which a core element (4) and a plurality sub-elements (5), which extend along the length of the preform, are arranged. In order to eliminate the high tendency to fracture during fusion and to ensure a fusion that is longitudinally stable and can be reproduced, according to the invention the sub-elements (5) and the core element (4) form a bundle (6) that is twisted at a specified angle around the longitudinal axis of the bundle (6a), wherein the pattern that is formed by the cross-sections of the sub-elements (5) and the cross-section of the core element (4) is maintained along the length of the preform (1), and subsequently, by heating beyond the transformation point of the materials thereof, is at least partially fused together, such that the material-free spaces (9, 10, 11) between the sub-elements (5), between the sub-elements (5) and the core element (4), and between the sub-elements (5) and the sheath (7) at least partially disappear.
