Claim:
1. A microstructured optical fiber, comprising: a core comprising a core material comprising hydrogen and/or deuterium bound to said core material; and a cladding comprising a cladding material; where at least a part of the core being of silica or doped silica and said core having a Germanium content of less than 0.001 at %; said microstructured optical fiber being a nonlinear fiber in that said microstructured fiber can guide light for at least a range of wavelengths λ said optical fiber being obtained by a method comprising loading said core material with hydrogen or deuterium under loading conditions suitable to allow the hydrogen or the deuterium to become bound to said core material, where the loading temperature T is equal to or more than 120° C. and wherein said fiber has been subjected to an anneal under conditions corresponding to a temperature T
