摘要：

A SiO2-ZrO2 nanostructured optical fibre is fabricated using the chemical sol-gel method associated to the drawing process; the structural and the waveguiding properties are studied. The refractive index difference (RIP) between the core and the cladding is 0.021 for a 30 mol% ZrO2 - 70 mol% SiO2 care composition. Illumination of the fibre 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, To control the nanostructure and the geometric parameters of the fibre, a preliminary study of the SiO2-ZrO2 binary system has been done, by X-ray diffraction (XRD), differential thermal analysis (DTA), thermo gravimetric analysis (TGA), transmission electron microscopy (TEM) and scanning electron microscopy (SEM); in addition the evolution of the sol viscosity with the time is studied.
