Buried ion-exchanged optical waveguides with refractive index profiles controlled by rediffusion

New buried optical waveguides whose refractive index profiles can be controlled by rediffusion are formed by the ion exchange and rf sputtering technique. A buried waveguide with a nearly symmetric refractive index distribution and a new slowly tapered structure are fabricated.
