A microstructured optical fiber for generating broadband white light having a core doped with germanium and silica cladding surrounding the core, the cladding including a plurality of holes arranged in the form of a regular mesh, wherein the diameter F of a hole in the cladding, the pitch L between the respective centers of two neighboring holes in the cladding, and the refractive index difference Dn between the germanium-doped fiber core and the silica of the cladding are such that the fiber can generate white light on the fundamental mode over a wavelength band having a width of at least 1000 nm.
