Optical and spectroscopic properties of soda-lime alumino silicate glasses doped with Er3+ and/or Yb3+

Abstract A new set of soda-lime alumino silicate (SLAS) glasses doped with a fixed percentage of Er 3+ and different percentages of Yb 3+ ions was produced by conventional melting process. Their spectroscopic properties, namely absorption and emission spectra, radiative and experimental lifetimes, were measured and are discussed here. Planar and channel optical waveguides were produced in these glasses by ion-exchange, and their characterization is reported as well.
