A microstructured multicore optical fibre (MMOF) includes a cladding in which a plurality of basic cells are formed that run along the MMOF. Each of the basic cells includes a core, and at least one of the basic cells is surrounded by a plurality of longitudinal areas that run parallel to the core along the MMOF and are arranged in a hexagonal arrangement around the core. The longitudinal areas are spaced by a lattice constant &#x39b;. Sides of the hexagon can be shared with adjacent basic cells.

Microstructured multicore optical fibre (MMOF), a device and the fabrication method of a device for independent addressing of the cores of microstructured multicore optical fibre

Microstructured multicore optical fibre with a microstructure area, in which, at least two basic cells are embedded, where each of them contains a core, preferably made of glass, specifically including doped silica glass or polymer, together with the surrounding it longitudinal areas with lower refraction index vs. that of the cladding, which areas may adopt the shape of holes, filled with gas, in particular with the air or a fluid or a polymer or spaces of another glass with doping allowing to reduce refractive index (further referred to as holes), embedded in a matrix of glass, in particular of silica glass or polymer. The refraction index of the holes is decreased vs. that of the matrix of glass, in particular of silica glass or polymer. The basic cell is characterised by the diameter of D2 core, the diameter of D3 core and the distance between adjacent holes, corresponding to lattice constant A. The centres of the holes are localised on the vertices and the middle points of the sides of the hexagon, the centre of which is designated by the core; the length of side c of the hexagon, created by the centres of holes, is equal to the preferably doubled lattice constant A. The juxtaposed, at least, two basic cells are surrounded by the cladding, preferably made of glass, in particular of silica glass or polymer. A Device for addressing cores of the multicore optical fibre a fabrication method of the device for addressing cores is also disclosed.
