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 >
