Soda-lime glass planar optical waveguides are fabricated by copper ion-exchange technique.The effective indices are measured by prism coupling method and the refractive index profiles of the planar waveguides are reconstructed by inverse WKB method.The properties of the prepared waveguides are affected by the time and temperature of the ion-exchange process.It was found that the modes and depth of the waveguides were not monotonic increasing with the ion-exchange time and temperature increasing,the number o...
