We have studied the fabrication and properties of the Cu(+)-containing waveguides. These waveguides were fabricated in a special soda-lime silicate glass as well as in commercial optical glass substrates, by using an ion exchange in the melts containing either Cu+ or Cu2+. at temperatures from 350 degrees C to 500 degreesC, and for periods from 5 min to 21 h. The optical properties of the fabricated wav eguides were characterized using both mode and photolumin escence spectroscopy. The composition of waveguiding laye rs was studied using Rutherford Backscattering Spectromet ry (RBS) and ESCA. The presence of divalent copper was de termined using Electron Paramagnetic Resonance (EPR). Aft er ion exchange, the refractive index increased, dependin g on the fabrication conditions, up to Deltan=+0.0693, an d the waveguides supported up to 16 TE and TM modes. The depths of the fabricated waveguides varied between 6.0 an d 27.5 mum.
