Abstract

A theory for optical waveguide fabrication processes, in which potassium ions exchanged into glass are used as a mask to regulate a subsequent silver-ion exchange, is presented.
The model is used to examine the use of this technique in restricting the width of narrow-channel waveguides.
The diffusion of silver through the potassium-ion mask is calculated, and a novel method of fabricating buried waveguides is described.
