| Abstract: | Thc Cs -Na ion exchahgc glass waveguides were made by both thermal diffusion and electrical fieldassista1lt diffusion methods. After the investigation of the temperature depcndence of the waveguides, it wasfound that these waveguides exhibit very high thermal stability below the glass transition temperature. Theion cxchangc mechanism of Cs -Na ion exchange was found to be non-Fick Diffusion. The stress gradientcanscd by the hugc dimension difference for Cs and Na ions, as the electroneutrality field gradientproduced duc to the largc difference in diffusion coefficients between Cs and Na ions predominate thediffusion process in ion exchange. The refractive index prohiles and concentration profiles obtained by SEMand X-ray cnergy dispcrsivc analysis call bc well cxplai11ed by thc proposed ion-exchange mechanism. |
