“…Although the absence of a supporting core tube introduces some additional fabrication complexity, effectively reduces the yield of first stage draws and makes the fabrication of reproducible fibres more challenging, fibres with "reduced" core thickness have nonetheless been fabricated. Experimentally they were shown to provide efficient suppression of surface modes, leading to very wide transmission bandwidths [6,7].…”

“…Since the larger central core hole requires comparatively lower pressure than the cladding holes to achieve the same expansion ratio, means to accurately control the pressure difference in different regions of the cane need to be implemented. Good quality HC-PBGFs were achieved in the past by passively pressurizing the canes in the second stage draw, i.e., by sealing their top face and exploiting self-pressurisation as a self-stabilising mechanism to control pressure variations [6][7][8]. More recent fibres, however, are typically produced by actively and independently controlling multiple pressure zones within the preform [9,10] in order to obtain a higher degree of control over the relative expansion of core and cladding holes.…”

Since the early conceptual and practical demonstrations in the late 1990s, Hollow-Core Photonic Band Gap Fibres (HC-PBGFs) have attracted huge interest by virtue of their promise to deliver a unique range of optical properties that are simply not possible in conventional fibre types. HC-PBGFs have the potential to overcome some of the fundamental limitations of solid fibres promising, for example, reduced transmission loss, lower nonlinearity, higher damage thresholds and lower latency, amongst others. They also provide a unique medium for a range of light: matter interactions of various forms, particularly for gaseous media. In this paper we review the current status of the field, including the latest developments in the understanding of the basic guidance mechanisms in these fibres and the unique properties they can exhibit. We also review the latest advances in terms of fibre fabrication and characterisation, before describing some of the most important applications of the technology, focusing in particular on their use in gas-based fibre optics and in optical communications.

We study the modal properties of feasible hollow-core photonic bandgap fibers (HC-PBGFs) with cores formed by omitting either 7 or 19 central unit-cells. Firstly, we analyze fibers with thin core surrounds and demonstrate that even for large cores the proposed structures are optimum for broad-band transmission. We compare these optimized structures with fibers which incorporate antiresonant core surrounds which are known to have low-loss. Trade-offs between loss and useful bandwidth are presented. Finally, we study the effects that small modifications to the core surround have on the fiber's group velocity dispersion, showing the possibility of engineering the dispersion in hollow-core photonic bandgap fibers.
