“…This technique consists of applying a direct-current (dc) electric field below the glass transition temperature (¹ ) and cooling the glass before removing the dc bias. The materials reportedly involved are mainly SiO -and TeO -based bulk oxide glasses (1)(2)(3)(4)(5). According to Myers et al, two different mechanisms can account for the induced second-order susceptibility (1,2):…”

“…This decay has been previously assumed to be the result of the formation of a cation-depleted near-surface layer at the anode side; this layer acquires a much higher resistivity than the bulk. [9] After ten minutes of poling treatment, the current reaches a saturation level that can be related to the surface current and/or the residual current present within the materials. In the case of 2S2G and S2G glasses, the poling current remains on a relatively high level (30-40 lA), it even slightly increases during the whole thermal treatment.…”

“…[2,5,7,8] This technique, used to break the centrosymmetry of the glass, consists of applying a high dc electric field while heating the sample at a temperature below its glass-transition temperature (T g ). According to Mukherjee et al, [9] the creation of the second-order nonlinearity lies in the existence of residual dc electric fields frozen within the sample after cooling and removing the applied dc voltage. Moreover, they proposed that the second-order susceptibility v (2) could be written as:…”

International audienceHigh second-order susceptibilities are created by thermal poling in bulk germanium disulfide based chalcogenide glasses. Experimental conditions of the poling treatment (temperature, voltage, time) were optimized for each glass composition. The second-order nonlinear signals were recorded by using the Maker fringes experiment and a second-order coefficient χ(2) up to 8 pm V-1 was measured in the Ge25Sb10S65 glass. This value is obtained using a simulation based on accurate knowledge of the thickness of the nonlinear layer. Two mechanisms are proposed to explain the creation of a nonlinear layer under the anode: the formation and the migration of charged defects towards the anode may mainly occur in Ge20Ga5Sb10S65 and Ge25Ga5S70 glasses, whereas the migration of Na+ ions towards the cathode may be responsible for the accumulation of negative charges under the anode in Ge33S67 and Ge25Sb10S65 glasses. Different electronic conductivity behaviors seem to be at the origin of the phenomenon. In parallel, the potential effect of the poling treatment on the structural and electronic properties is studied using Raman spectroscopy and secondary ion mass spectroscopy measurements

“…They obtained F 2 1 pm/V in molten quartz glass by poling at high temperature. Furthermore, Myers and colleagues explained the origin of this nonlinearity by a model of charge movement and orientation during poling [8,9]. Nasu and colleagues proposed a model based on OH bonding in glass [10,11].…”
