Planar waveguides obtained on commercial glass substrates by sol-gel and laser irradiation methods

Abstract

The aim of the thesis is the fundamental study, design, fabrication and characterisation of photonic structures for spatial optic and, particulary, the interconnexion of optical devices. The research explored technologies and substrates for the fabrication of photonic structures based on the guided propogation of light and its application to research and development of integrated optical devices and improving the functionality of communication systems, which realises intelligent optical operations based on Fourier spatial transformed and image formation properties.At the same time, aims to explore new technologies for fabrication ofphotonic structures; which are repeatibility and not contaminants; and the product of well-defined charactericstics and low price.
