Abstract: The invention relates to a micro-structured optical fiber suitable for supercontinuum generation a preform therefor, a method of production thereof and a supercontinuum light source. The optical fiber comprises a core microstructured length section L cm , which comprises: a micro-structured core region comprising at least a first region forming a central part of the core region and a second region surrounding the first region; and a cladding surrounding the core region; wherein the first and second regions are of a first and second silica material, respectively, which differs with respect to composition, and wherein the core region in at least a length part of the core microstructured length section L cm has a cross sectional diameter D cm perpendicular to the longitudinal axis which is about 8 μm or less.
