Paper Abstract

Efficient second-harmonic generation (SHG) was recently observed in centrosymmetric doped glass f'ibrest'2. Two processes are important for forming gratings in doped fibres, namely, the excitation of dopant defects, and the creation and alignment of permanent dipoles in the fibre core. Positively and negatively charged color centers are assumed to be generated owing to two 3- or higher-order-photon absorption. Electric dipoles can be created within strings of interconnected dopant defects only3. It seems very likely that the dopant-defect strings are dominantly oriented along the fibre due to the layer structure of dopant distribution and the drawing process.
