ABSTRACT:
Ionic drift in integrated optical devices is reduced by the utilization of a gettering layer interposed between the surface dielectric and the electrodes. The material used to form this layer is capable of gettering the mobile ions at a relatively low temperature (for example <600.degree. C.).
