Journal ArticleDOI
Recent advances in chalcogenide glasses
Bruno Bureau,Xianghua Zhang,Frédéric Smektala,Jean-Luc Adam,Johann Troles,Hongli Ma,Catherine Boussard-Plédel,Jacques Lucas,Pierre Lucas,David Le Coq,Mark R. Riley,Joseph H. Simmons +11 more
TL;DR: In this article, the spectral analysis of biomolecules present in human lung cells by measuring their infrared signatures was performed using 77Se NMR spectroscopy, which is a useful tool for checking the local environment of the Se atoms.
Journal ArticleDOI
Multi-milliwatt mid-infrared supercontinuum generation in a suspended core chalcogenide fiber
Uffe Møller,Yi Yu,Irnis Kubat,Christian Rosenberg Petersen,Xin Gai,Laurent Brilland,David Mechin,Celine Caillaud,Johann Troles,Barry Luther-Davies,Ole Bang +10 more
TL;DR: A low-loss suspended core As(38)Se(62) fiber with core diameter of 4.5 μm and a zero-dispersion wavelength of 3.5μm was used for mid-infrared supercontinuum generation and was in good correspondence with the calculated dispersion.
Journal ArticleDOI
Experimental and theoretical study of higher-order nonlinearities in chalcogenide glasses
Georges Boudebs,S. Cherukulappurath,Hervé Leblond,Johann Troles,Frédéric Smektala,François Sanchez +5 more
TL;DR: In this article, the nonlinear properties of two distinct chalcogenide glasses were investigated experimentally and theoretically through a spatially resolved Mach-Zehnder interferometer, and it was shown that the resulting nonlinear index coefficient cannot be correctly described with the usual cubic model.
Journal ArticleDOI
Microstructured chalcogenide optical fibers from As(2)S(3) glass: towards new IR broadband sources.
Mohammed El-Amraoui,Grégory Gadret,J-C Jules,Julien Fatome,Coraline Fortier,Frédéric Désévédavy,I. Skripatchev,Younes Messaddeq,Johann Troles,Laurent Brilland,Weiqing Gao,Takenobu Suzuki,Yasutake Ohishi,Frédéric Smektala +13 more
TL;DR: The use of a versatile process using mechanical drilling for the preparation of preforms and then the drawing of MOFs including suspended core fibers for low losses MOFs are described, with background level of losses reaching less than 0.5 dB/m.
Journal ArticleDOI
Strong infrared spectral broadening in low-loss As-S chalcogenide suspended core microstructured optical fibers
Mohammed El-Amraoui,Julien Fatome,Jean-Charles Jules,Bertrand Kibler,Grégory Gadret,Coraline Fortier,Frédéric Smektala,I. Skripatchev,C. F. Polacchini,Younes Messaddeq,Johann Troles,Laurent Brilland,Marcin Szpulak,Gilles Renversez +13 more
TL;DR: The fabrication and characterization of the first guiding chalcogenide As(2)S(3) microstructured optical fibers with a suspended core with a zero dispersion wavelength (ZDW) is reported.
