摘要

A hollow core photonic bandgap optical fibre comprises: a cladding comprising capillaries in a hexagonal array and a hollow core formed by excluding a hexagonal group of nineteen capillaries from the centre of the hexagonal array. The core is inflated. A core size ratio is 1.26 or above, defined as a ratio of the core diameter to the cladding diameter normalized to the ratio of the core diameter to the cladding diameter in an undistorted hexagonal array; a first ring ratio is between 0.55 and 2.50, defined as a ratio of the length of radially aligned struts separating the capillaries of the first ring to the length of a strut in an undistorted hexagonal array; and a core node spacing is between 0.60 and 1.90, where defined as a ratio of a strut length around the core of a largest corner capillary and a strut length around the core of a smallest side capillary. The fabrication method comprises four different pressures for the core, corner capillary, side capillary and cladding.
