Abstract

The paper presents measurement results of the refractinve profiles of planar waveguides produced in glass BK-7 and in sodium-silica glass using the ion-exchange technique Ag+↔Na+ from the solutions AgNO₃-NaNO₃. The refractive profiles were reconstructed with the use of modal equation basing on the measured propagation constants of modes for the wavelength 677 nm for both polarization states. We applied AgNO₃ solutions in NaNO₃ in molar ratios within the range 5.1*10-4-9.97*10-3 at temperatures ~380°C. Process times were within the range from several to 48 hours. As indicated by the obtained investigation results, the shape of the obtained profile can be controlled by an appropriate selection of admixture bath composition.
