Paper Abstract

Conventional optical fibre structures are typically based on circular symmetric core and cladding profiles. The introduction of additional micro- and nano-structures greatly enhances the possible functionality of such optical fibres. Such additional structures may be implemented locally (e.g. Bragg gratings, surface gratings) or may be incorporated in the core or cladding structure (e.g. photonic crystal fibres, multicore fibres). Especially hole-assisted fibres have become increasingly interesting for different types of applications not only in optical communication but also for fibre light sources and amplifiers and in optical sensing. Due to holey structures, optical transmission properties in terms of wavefield distribution, numerical aperture or dispersion can be modified, or new light guiding principles like bandgap guiding can be applied. Multicore arrays represent structures where several partial wavefields from separate cores may interact. Local structures on or within a fibre allow local modification of guided wavefields. In this way, e.g., the spectral properties are modified or options for switching are introduced.
