Paper Abstract

We propose a two step ion exchange process to minimize the losses in silver ion-exchanged waveguides using aluminum as mask material. In a first step the sample with the Al-layer is treated in sodium nitrate in order to oxidize the aluminum. The second step involves an ion exchange in an AgNO3/NaNO3 salt mixture. We applied this method to prepare strip waveguides in a special glass substrate, BGG31, used for telecommunication devices. The low losses of the strip waveguides in BGG31 are important for applications such as integrated optical laser amplifiers that we suggest in this paper.
