Fabrication and Applications of Low OH Photonic Crystal Fibres

I Gris Sanchez

Research output: ThesisDoctoral Thesis

Abstract

The aim of this thesis is to consistently fabricate low OH content silica solid-core photonic
crystal fibres of different core diameters, identified as low spectral attenuation at 1383 nm.
Three different methods are proposed. Two of them are focused on preventing the OH
contamination of glass during fabrication whilst the third method is focused on obtaining low
OH fibres by reducing the OH content of already contaminated glass. The local attenuation
at the ends of these low OH fibres is notoriously worsen when they are exposed to the
atmospheric water vapour, the levels of this attenuation depending very strongly with core
diameter. The low OH levels achieved (0.19 ppm) in the small-core photonic crystal fibres
open the scope to applications in non linear optics where standard levels of absorption
are detrimental. In particular, the principle of a widely tunable source (across the OH
absorption peak at 1383 nm) delivering femtosecond pulses beyond 2 μm is demonstrated
experimentally.
