[UNESP]Made available in DSpace on 2018-12-11T16:38:35Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; This paper reports on the fabrication and characterization of waveguides inside of a dye doped-organic/inorganic bulk material using femtosecond laser microfabrication. Rhodamine B-doped GPTS/TEOS-derived organic/silica monolithic xerogels with excellent optical quality were prepared by sol-gel method. ...
Influence of lattice modifier on the nonlinear refractive index of tellurite glass
Santos, F. A.; Figueiredo, M. S.; Barbano, E. C.; Misoguti, L.; Lima, S. M.; Andrade, L. H.C.; Yukimitu, K. [UNESP]; Moraes, J. C.S. [UNESP]Made available in DSpace on 2018-12-11T16:48:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-12-01; We studied the influence of different lattice modifiers (Nb2O5, Bi2O3, or TiO2) on the nonlinear refractive index of a tellurite glass matrix by using the Z-scan technique. Based on the ability of the lattice modifiers to decrease the band-gap energy while simultaneously increasing the linear refractive...
