| Abstract Scope |
Copper containing optical waveguides as promising candidates for applications in sophisticated integrated optics structures operating in visible/NIR spectral regions were fabricated by ion exchange of Cu+ and/or Cu2+ in specially formulated glasses having different optical basicity and containing optionally also erbium and by Ag+ exchange in copper containing novel glasses. The crucial factor of their function is oxidation states of Cu and how to affect it by preparation conditions and the substrate glass. These factors were evaluated by measuring the characteristics of the waveguides as their mode spectra, depth concentration profiles of Cu/Ag ions and photoluminescence properties. The Cu+ containing samples had very strong blue-green luminescence, which wavelengths was strongly affected by locations (coordination) of the Cu+ ions in the glass matrixes depending on the composition of the glass and allowing thus for feasible tuning the wavelength of the emission.
