We demonstrate improvements to the double ion-exchange process proposed for the fabrication of synthetic diffractive optical elements in glass waveguides. In this process a potassium slab waveguide is first fabricated. Then the diffractive element is made with silver ion exchange. In the modified process a short silver ion exchange is used in the second process step and the double ion-exchanged waveguide remains single mode. The undesired undiffracted light can be nearly totally eliminated. The mode profile of the potassium and double ion-exchanged waveguides are very close to each other resulting in low coupling loss between these two waveguide regions.
