title: UV-irradiation-induced structural transformation of germanoscilicate glass fiber.
abstract: Raman spectra of germanosilicate core fibers before and after UV irradiation were investigated. Significant changes of the Raman spectra after irradiation indicate transformation of the glass structure. A possible interpretation of the observed changes is proposed.
