New setup for end-fire coupling excitation of planar waveguides at low temperatures

Autor: M.C. Marco de Lucas, Bernard Jacquier, J. Y. Rivoire, B. Varrel, Eric Lebrasseur

Publikováno v: Review of Scientific Instruments. 68:2275-2278

This work describes a new experimental setup for end-fire coupling excitation of planar waveguides in the 300–10 K temperature range, which allows us to analyze their optical and spectroscopic properties through different techniques such as transmi

IR luminescence decays and radiative lifetime of the level in Er3+ doped sol-gel TiO2 planar waveguides

Autor: J. Mugnier, M.C. Marco de Lucas, Bernard Jacquier, B. Varrel, A. Bahtat, Mohamed Bouazaoui

Publikováno v: Optical Materials. 7:173-179

The lifetime of the 4 I 13 2 level has been analyzed in erbium doped TiO2 sol-gel planar waveguides as a function of the Er3+ concentration and thermal treatments in the way of testing their potentially for optical amplification at 1.53 μm. Luminesc

Low-energy excitations in polyvinyl chloride: Raman scattering and thermal properties

Autor: R. Calemczuk, A. Boukenter, B. Salce, Eugène Duval, T. Achibat, B. Varrel

Publikováno v: Journal of Non-Crystalline Solids. 190:258-263

The low-energy excitations of a very fragile glass-former (in the sense of Angell), poly(vinyl chloride), have been studied by low-frequency Raman scattering and by measurements of the low-temperature heat capacity and thermal conductivity. Two diffe

Publikováno v: Radiation Effects and Defects in Solids. 135:397-399

We report the physical properties of a new fast indium-based scintillator. The technique of elaboration and the crystal structure of indium disilicate (In 2 Si 2 O 7 ) are presented as well as the analysis of an intense ultraviolet photoluminescence

Effect of annealing temperature on TiO2 monolayer thin films as studied by waveguide raman spectroscopy and electron microscopy

Autor: J. Serughetti, J. Mugnier, M. Bahtat, C. Bovier, B. Varrel

Publikováno v: Journal of Materials Science Letters. 11:875-877

The crystallographic form of TiO 2 is only anatase in the temperature range studied. The very low-frequency Raman scattering provided the mean diameter of the particles, which correspondded with electron microscopy results. The progression of this me
