Abstract
The present paper describes the fabrication of optical channel waveguides in an Er3+-doped Bi2O3-based glass using direct laser writing with a UV beam at 244 nm. A buried positive refractive index change was achieved through this method and a description of the observed phenomena is given, based on optical and electron microscopy.
