Abstract

Planar-graded index optical waveguides have been fabricated in soda lime glass substrates by silver (AG⁺) ion exchange in a mixed melt of silver nitrate (AgNO₃), potassium nitrate (KNO₃) and sodium nitrate (NaNO₃). The propagation mode indices measured agree well with the theoretical WKB dispersion relation of J. W. White and P. F. Heidrich (1976) using a second-order polynomial function for the refractive index profile. The surface index change can be varied from 0.09 to 0.004 by changing the amount of AgNO₃ in the mixed nitrate melt, and effective diffusion coefficients have been calculated for these waveguides.
