Abstract
A microstructured optical fiber has a core region with a material having a refractive index nand a microstructured region surrounding the core region with a background material having a refractive index nwhich is lower than the refractive index n. The microstructured region has a plurality of microstructures having a refractive index different from the refractive index n, wherein the distance Δbetween the centers of any couple of adjacent microstructures is at least equal to about λand not higher than about 1.5λ, wherein λis the spatial variation length of the electric field intensity in the microstructured region.
