Paper Abstract

A characterization of diluted silver ion-exchanged waveguides in glass substrates was carried out for three different wavelengths, (lambda) equals 0.6328 micrometers , 1.152 micrometers , and 1.523 (mu) , by using an improved WKB method which correctly calculates the phase shift at the diffused boundary, hence eliminating calculation errors in the theoretical dispersion curves mostly in single mode regions and near other mode cutoffs. The results show a significant improvement in the agreement between the theoretical WKB dispersion curves and the measured mode indices.
