Hollow Core Photonic Bandgap fibers for Telecommunications: Opportunities and Potential Issues (original) (raw)
Hollow-core photonic bandgap fibers: technology and applications
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.

Hollow core-photonic bandgap fibers (HC-PBGFs) have many intriguing properties including ultralow nonlinearity and low latency relative to conventional (solid) forms of optical fiber. As a consequence they are of great interest as a potential transmission medium in next-generation optical communication systems. However, in order to have any chance of competing with conventional transmission fibers, the possibility of achieving low loss over a suitably extended bandwidth needs to be demonstrated.

Classification of the Core Modes of Hollow-Core Photonic-Bandgap Fibers
IEEE Journal of Quantum Electronics, 2000
Using a new full-vectorial finite-difference mode solver utilizing a hexagonal Yee's cell, we calculated the dispersion diagram of a slightly multimode (16 modes) air-core photonic-bandgap fiber (PBF) and the electric-field profiles of all of its core modes. Careful comparison shows striking similarities between these properties and those of the hybrid modes of a conventional step-index fiber, in terms of the modes' field profiles, the modes' degeneracy, the order in which the modes mode cut off in the wavelength space, and the maximum number of modes. Based on these similarities, we propose for the first time a systematic nomenclature for the modes of a PBF, namely hybrid HE and EH modes and of quasi-TE and quasi-TM modes. Other small but relevant similarities and differences between the modes of these two types of fibers are also discussed.
