| Abstract: | For the first time, it is experiementally verified that the index profile of K -Na ion-exchanged waveguide in CdSxSe1-x doped glass follows a second-order polynomial distribution. Mode-dispersion curves have been obtained by computing simplified mode equation in WKB approximation and verified by experiment. Diffusion constant has been measured accurately. Technical basis is provided for the design and fabrication of all-optical switching devices in this kind of nonlinear waveguide. |
