Abstract :
A simple and reproducible technology is developed for the fabrication of low-loss silica waveguides on silicon substrates. The guiding layer is formed by changing the Si-O ratio composition of the SiO2 layer. The waveguides can be made to have a good match to either optical fibres or guided-wave devices in III-V compound semiconductors.
