Abstract
A hollow-core photonic bandgap fiber having 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, wherein a ratio between a difference in a length of a longest and shortest pitch spacing of the nodes at the core boundary to an average pitch spacing at the core boundary is less than about 0.3.
