Abstract :
The diffusion profile of a stripe optical waveguide formed by ion exchange has been calculated. A finite-difference technique was used to solve the nonlinear ion-exchange equation in two dimensions. The effect of employing a metallic rather than a nonconducting mask is to significantly reduce the width of the diffused stripe.
