摘要： Microstructured optical fibre with selectively enlarged spaces of reduced refraction index, especially for the generation of non-linear effects and stress measurements with a ring configuration of spaces, located around a cladded core, where the spaces demonstrate cross-section shape close to circle and decreased diffraction index, especially for the generation of non-linear effects and stress measurements, made of glass, preferably of silica glass or polymer and are located in nodes of hexagonal lattice with distances between the lattice nodes equal to the lattice constant, in which, around a single-mode core, there are, at least two rings with spaces of decreased diffraction index, filled with gas or fluid or a polymer, where the diameter of every-second space with decreased diffraction index in, at least, one ring, is enlarged to be lower from the double lattice constant, while the diameters D of all the enlarged spaces with decreased diffraction index are similar in size and the diameters d of non enlarged spaces with decreased diffraction index are close in size and lower from the lattice constant and the ratio of the diameter d of non enlarged space to the lattice constant is within the range from 0.30 to 0.45.
