Paper Abstract

The index change induced by two-photon absorption of green light in Ge-doped optical fiber is partly anisotropic. We review the experimental facts that form the basis for a physical model of bleachable oriented defects. We also describe how a density matrix formalism, based on a simili three-level system, can be used to determine the tensorial properties of the photoinduced index change.
