Show more >The ability to shape the refractive index of silica-based optical fibres is an important challenge to tackle for flexible engineering, in search of new applications and future optical fibre designs. The approach of stacking several hundred of capillaries of pure and doped silica to obtain fibres with a gradient index [1-2] has recently been demonstrated. This method, known as nanostructuring, is based on the Maxwell-Garnett approximation of effective media theory [3], because the size of each element in the fibre core decreases to the nanometric scale. It gives access to myriad structures with circular symmetry and enriched passive and active element-doped fibre designs. Nanostructuring also makes it possible to induce optical properties such as birefringence [4].An approach of developing fully solid polarisation-maintaining (PM) fibres was established in the early 1980s and has not progressed significantly since. Commercially available PM fibres are based on stress-induced birefringence or core ellipticity, which represents a compromise between polarisation-maintaining functionality and compatibility (in terms of optical and mechanical properties) with telecommunications systems. However, PM fibres with stress-applied parts (SAPs) in the cladding are impractical for the creation of multi-core fibres, as SAPs can lead to much larger cladding diameters than for an optimal single-mode fibre. This is incompatible with the idea of multi-core fibres, where stacking/packaging of multiple cores in a minimal volume with negligible cross-coupling between cores is a crucial requirement. A new PM fibre concept is therefore needed to meet these PM-multi-core fibre demands.Show less >
