Nanostructured optical fiber by the sol-gel process in the SiO2-ZrO2 system

International audienceA SiO2-ZrO2 nanostructured optical fiber developed using the chemical sol-gel method is fabricated and its waveguiding properties are studied. The refractive index difference between the core and the cladding is 0.021 for a (30%ZrO2-70%SiO2) molar core composition. Illumination of the fiber with a supercontinuum source (350-1750 nm) shows that the light is guided over this entire range. The measured attenuation losses are 0.7 dB/m at a 1064 nm wavelength and the calculated cutoff wavelength is 714 nm

Advances in original fibres fabrication using innovative techniques

International audienceThe development of original technologies to fabricate new kinds of fibres is presented here. First of all, the sol-gel process is developed to achieve fibres with original properties of waveguiding (new wavelength of emission of rare earths or transition metals, ultraviolet waveguiding): either a fibre composed of doped nanocrystals in a silica matrix or fibres composed of a one dimensional photonic bandgap structure. In this way, high refractive index dielectric oxides like ZrO2, TiO2 are studied. Secondly, the core suction technique associated with the stack and draw process is developed to fabricate fibres with various glasses and then, original profiles of refractive index to achieve multiwavelength laser
