The Effect of Laser Heating on Optical Properties of Germania Doped Silica Optical Waveguides
Published online by Cambridge University Press: 25 February 2011
Abstract
We report the use of CO2 laser heating for inducing an increase in the refractive index of germania doped silica films. UV absorption spectroscopy and XPS analysis have confirmed that the index change is a result of GeO2 being reduced to GeO. The technique has been successfully used for the direct writing of integrated optical strip waveguides.
