Paper Abstract

Integrated optical components in glass are commonly fabricated by a thermal or a field assisted ion exchange. Applying an elctrical field reduces the ion exchange time drastically. Usually the process is performed at fixed voltages and different exchange times1 . We realized that reproducibility is accompanied with great difficulties using this technique. A reproducible fabrication of optical waveguides is achieved by using the exchanged charge as the determining process parameter. The ion current is integrated by a control unit which automatically terminates the exchange process when the preset charge is reached. The charge corresponds to the amount of exchanged ions and a reproducible process is available.
