    Abstract: The disclosure relates to a microstructured optical fiber (20) comprising a core region (22) and a cladding region (24) which surrounds the core region. The cladding region comprises a plurality of cladding features (21, 26) within a cladding background material, wherein the cladding region comprises an inner cladding region (27) with at least one ring of inner cladding features (21) and an outer cladding region (28) with at least three outer cladding rings of outer cladding features (26). The inner cladding features have a first characteristic diameter and the outer cladding region comprises a plurality of outer cladding features having a second characteristic diameter. Each ring of inner cladding features comprises bridges of cladding background material having an average minimum width W 1 separating the cladding features, and each ring of outer cladding features comprises bridges of cladding background material having an average minimum width W 2 separating the cladding features. The average minimum width W 2 is at least about 10% larger than the average minimum width W1 and the core region has a diameter of at least about 2 μιη. The disclosure moreover relates to a cascade optical fiber with at least one fiber according to the disclosure as well as a source of optical supercontinuum generation.
