“…For instance, in the particular system (1Àx)(0.95NaPO 3 +0.05Na 2 B 4 O 7 )+xNb 2 O 5 , both second (w (2) ) and third (w (3) ) order optical susceptibilities increase significantly with the niobium content [6,10,11]. At the opposite, in the system (1Àx)(0.9 Ca(PO 3 ) 2 +0.1 CaB 4 O 7 )ÀxNb 2 O 5 , x ¼ 0-50 [12,13], w (3) values increase with the niobium oxide concentration and the induced w (2) remain quite constant in the range 0.42-0.5 pm/V. For these two particular systems, i.e.…”

International audienceThermally poled niobium borophosphate glasses in the system 0.55(0.95−y) NaPO₃+y/2 Ba(PO₃)₂+0.05Na₂B₄O₇)+0.45Nb₂O₅ were investigated for second order optical nonlinear (SON) properties. Bulk glasses were studied by Raman spectroscopy, thermal analysis, optical and dielectric measurements. The sodium to barium substitution does not lead to significant changes in optical properties, crystallization of glasses and coordination environment of polarizable niobium atoms. However, the ionic conductivity decreases drastically with the increase of barium concentration. Secondary ion mass spectroscopy has been used to determine the element distribution in the anode layer of the thermally poled glasses. The second order optical susceptibilities gradually decrease from χ⁽²⁾=2.8 pm/V to zero with the increase of barium content. Using a simple electrical model, variations of nonlinear optical responses have been correlated with dielectric characteristics

“…Glassy thin films appear to be serious candidates in this domain of applications as they can exhibit low losses, 1-3 high amplification by rare earth doping, [4][5][6] and efficient second order nonlinear optical properties induced by thermal poling. [7][8][9] In this family of amorphous materials, lead-germanate glasses are attractive systems because of their large ͑3͒ nonlinearity and significant photosensitivity that may lead to efficient optical grating and feedback structures. 10,11 Glass thin films can be prepared by different deposition techniques, among which pulsed-laser deposition ͑PLD͒ is a relatively quick and simple technique.…”

Lead-germanate materials are attractive systems for photonics applications. In this context, amorphous lead-germanate films were grown by pulsed-laser deposition at different substrate temperatures and oxygen pressures using a glassy target of composition 0.4PbO -0.6GeO 2 . Optical and infrared measurements showed that the substrate temperature has a strong influence on the optical quality and stability of the deposited films. An accurate characterization of films was achieved by comparing experimental and simulated transmittance spectra in the infrared, and allowed to probe the structural evolution and variations in composition as a function of oxygen pressure. The results showed that the difference in reactivity of lead and germanium toward oxygen in the laser-produced plasma allows for composition adjustments in the lead-germanate films by varying the oxygen pressure in the deposition chamber.
