Paper Abstract

The photosensitivity of germanium-doped silica glass fibers and related phenomena, namely photoinduced second harmonic generation and refractive index change, attract considerable interest. In the present paper the microscopic mechanisms of the photosensitivity, which are based on photoionization and structural transformation, are considered. The recent experimental results, which reveal the role of excited triplet state of germanium oxygen deficient defect in the photosensitivity of germanium-doped glass, are discussed.
