“…However, the many kinds of defects and many high energy lone pair electrons are expected to cause large second harmonic generation. 5 In chalcogenide glasses, Ge-S system has high transparency in S-rich composition, and thus this paper reports the second harmonic generation of Ge-S glass system and discusses the mechanism by electron spin resonance ESR and Raman scattering technique for the samples before and after the poling.…”

“…Some of them are poling under irradiation of UV light called photoinduced, 3 using seed laser incident beam called optical poling 4 and corona poling. 5 With respect to the mechanism, the orientation of dipoles and the process through x 3 are still controversial. But, the large second harmonic generation values have been obtained for UV-poled SiO 2 glass, 3 and optical-poled As 2 S 3 glass.…”

Second harmonic generation was observed from thermally poled GeS x xࢼ3, 4, 5, 6 glass system. The intensity of second harmonic generation depended on the S content. From xࢼ3 to 5, the generation increased with increasing S content, and then decreased at xࢼ6. There was apparent dependence of the second harmonic generation on poling temperature. The maxima appeared by poling at near glass transition temperature. By electron spin resonance and Raman scattering measurements before and after poling, it is evident that defects were formed by poling and the structure was deformed, which could relate to the generation. The relaxation of the generation was interpreted according to a recombination of defects and to a relaxation of structural deformation.

“…In this context, recent works have demonstrated that large values of second order nonlinear optical coefficient ͓ ͑2͒ ͔ can be obtained in thermally poled inorganic glasses or transparent glass ceramics. [1][2][3] Because of the good thermal, optical, and mechanical stabilities of such materials, they can be considered as potential candidates in this domain.…”

Micro-Raman analysis has been carried out on the cross section of thermally poled sodium-niobium borophosphate glasses. We were able to measure with accuracy an enhanced Raman response from the nonlinear optical ͑NLO͒ layer formed at the anode side of the poled glasses. The thickness of the NLO layer has been estimated. Several spectral changes were observed within this layer, which manifest important structural rearrangements after thermal poling. Possible mechanisms leading to structural reorganization in the space charge region are discussed.

“…Whilst this paper is concerned with silicate glasses it is important to note that poling has been performed on various other glasses, including tellurite, 42) chalcogenide, 43) silicon oxynitride, 15) and on other materials including polymers and of course non-linear crystals such as LiNbO3. This section considers the poling of several different bulk silicate glasses.…”
