Paper Abstract

Cs+- and K+-exchange in a neodymium-doped soda-silicate glass is investigated. The Nd-concentration is about 4.6(DOT)1020/cm3. K+- exchange generates erfc-profiles with N.A. equals 0.16, whereas Cs+-exchange results in steplike profiles (N.A. equals 0.32). Monomode as well as multimode operation is possible. Stripe waveguides have been formed by thermal K+-exchange using Al- masks with openings from 3 to 10 micrometers . The fluorescence spectrum is not affected by the ion exchange process.
