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.

Microstructured optical fiber and a device for generating broadband white light

The invention relates to the field of amplifying or emitting optical fibers. It comprises an amplifying optical fiber doped with a rare earth comprising a plurality of successive segments (), presenting a monomode core and a multimode core, presenting at the periphery of the multimode core a peripheral segment () of low index so as to increase the numerical aperture of the optical fiber, outer cladding () being situated at the periphery of the low index peripheral segment (), the multimode core being at least in part above the outer cladding (), the peripheral segment () presenting a decreasing gradient shape.

Optical fiber for amplification or for laser emission

An optical fiber with microstructures comprises a plurality of capillary tubes disposed around a central rod and including a self-cleaning layer including molecules able to react with hydroxyl molecules to produce volatile gaseous substances.
