Characterization of thermally poled germanosilicate thin films
(Optical Society of American (OSA), 2004)We report measurements of the nonlinearity profile of thermally poled low-loss germanosilicate films deposited on fused-silica substrates by PECVD, of interest as potential electro-optic devices. The profiles of films grown ... -
Infrared absorption spectroscopy of monolayers with thin film interference coatings
(Optical Society of America, 2017)We report high performance Infrared spectroscopy platforms based on interference coatings on metal using CaF2 dielectric films and Ge2Sb2Te5 (GST) phase-change films. IR vibrational bands of proteins and organic monolayers ... -
Plasma enhanced chemical vapor deposition of low-loss as-grown germanosilicate layers for optical waveguides
(SPIE, 2004)We report on systematic growth and characterization of low-loss germanosilicate layers for use in optical waveguides. Plasma enhanced chemical vapor deposition (PECVD) technique was used to grow the films using silane, ... -
Theoretical study of the insulating oxides and nitrides: SiO2, GeO2, Al2O3, Si3N4, and Ge3N4
(Springer New York LLC, 2007)An extensive theoretical study is performed for wide bandgap crystalline oxides and nitrides, namely, SiO2, GeO2, Al 2O3, Si3N4, and Ge3N 4. Their important polymorphs are considered which are for SiO 2: α-quartz, α- and ... -
Thermally poled germanosilicate films with high second-order nonlinearity
(IEEE, 2005)Accurate measurements of the second-order nonlinearity profile of thermally poled low-loss germanosilicate films grown on fused-silica substrates are reported, of interest as potential electro-optic devices. After optimization, ...
