Abstract

Integrated optic lasers and amplifiers have been demonstrated in neodymium-doped glasses. These devices have operated near 1057 nm in silicate glasses and 1057 and 1355 nm in phosphate glasses [1,2,3]. Laser action at 905 nm has been realized in neodymium-doped-silica fiber lasers but not in glass integrated optic devices [4]. Ion exchange from silver films is attractive for integrated optic waveguide fabrication since it is a dry process which does not use molten salts. We have fabricated low-loss waveguides in a neodymium-doped phosphate glass by ion exchange from silver films. CW lasing was achieved at 905, 1057 and 1356 nm in the same device.
