Electro-thermal poling in bioactive sodium‑calcium phosphate-silicate glass: Anodic near-surface network connectivity changes and second harmonic generation

Autor: D. Palles, M. Dussauze, C.R. Mariappan, V. Rodriguez, B. Roling, E.I. Kamitsos

Publikováno v: Journal of Non-Crystalline Solids: X, Vol 17, Iss , Pp 100164- (2023)

We report Raman spectra in the sub-anodic region after electro-thermal poling of the 46S4 bioglass and show a correlation between structural changes and the induced second harmonic generation (SHG). The Raman peak at ca. 625 cm−1, due to the symmet

Crystallization of potassium titanosilicate glass under thermal poling using a profiled anode

Autor: Reshetov Ilya, Redkov Alexey, Melehin Vladimir, Zhurikhina Valentina, Lipovskii Andrey

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 15, Iss 1 (2022)

This paper is devoted to in-depth study of the crystallization process in the K2O-TiO2-SiO2 glass under thermal poling using a profiled anode and heating temperature below the glass transition temperature. The crystallization was investigated by Rama

SHG in Micron-Scale Layers of Glasses: Electron Beam Irradiation vs. Thermal Poling

Autor: Ilya Reshetov, Vladimir Kaasik, Gennadiy Kan, Sergey Shestakov, Sergey Scherbak, Valentina Zhurikhina, Andrey Lipovskii

Publikováno v: Photonics, Vol 9, Iss 10, p 733 (2022)

In this work, we studied the introduction of second-order optical nonlinearity (SON) into subsurface layer soda-lime and alkali-free flint glasses using two different techniques: electron beam irradiation and thermal poling in an open anode configura

Second‐Order Optical Response in Electrically Polarized Sodo‐Niobate Amorphous Thin Films: Particularity of Multilayer Systems

Autor: Lara Karam, Frédéric Adamietz, Dominique Michau, Ganapathy Senthil Murugan, Thierry Cardinal, Evelyne Fargin, Vincent Rodriguez, Kathleen A. Richardson, Marc Dussauze

Publikováno v: Advanced Photonics Research, Vol 2, Iss 6, Pp n/a-n/a (2021)

Herein, our attention is focused on the second‐order optical properties of thermally poled sodo‐niobate amorphous thin films through an original methodology that combines both macroscopic and microscopic second harmonic generation techniques. By

Visualization of Spatial Charge in Thermally Poled Glasses via Nanoparticles Formation

Autor: Ekaterina Babich, Ekaterina Lubyankina, Vladimir Kaasik, Alexey Mozharov, Ivan Mukhin, Valentina Zhurikhina, Andrey Lipovskii

Publikováno v: Nanomaterials, Vol 11, Iss 11, p 2973 (2021)

It is shown for the first time that the vacuum poling of soda-lime silicate glass and the subsequent processing of the glass in a melt containing silver ions results in the formation of silver nanoparticles buried in the subanodic region of the glass

Thermal Poling of Optical Fibers: A Numerical History

Autor: Francesco De Lucia, Pier J. A. Sazio

Publikováno v: Micromachines, Vol 11, Iss 2, p 139 (2020)

This review gives a perspective of the thermal poling technique throughout its chronological evolution, starting in the early 1990s when the first observation of the permanent creation of a second order non-linearity inside a bulk piece of glass was
