Production and characterization of Tm3+/Yb3+ codoped waveguides based on PbO–GeO2 thin films

Photoinduced Charge Transfer versus Fragmentation Pathways in Lanthanum Cyclopentadienyl Complexes

“…1−3 Lanthanide oxide thin films have applications as waveguides in optics, due to their high refractive index, large bandgap, and low phonon energy. 4,5 Other applications include protective and corrosion-resistive coatings 6,7 and phosphors. 8 Metal−organic chemical vapor deposition (MOCVD) and atomic layer deposition (ALD) techniques have been employed to grow lanthanide oxide thin films using a number of precursors including lanthanide cyclopentadienyl complexes.…”

Upconversion emission in antimony–germanate double-clad optical fiber co-doped with Yb3+/Tm3+ ions

“…Upconversion emission from rare-earth ions co-doped optical fibers have attracted much attention due to wide range of applications: solid-state lasers and amplified spontaneous emission sources, optical data storages, biomedical diagnostic, sensors and 3D multicolor displays [5][6][7][8][9][10]. The study of blue upconversion emission in Yb 3+ /Tm 3+ ions co-doped glasses and optical fibers has become a focus of research in recent years [11][12][13][14][15]. It results from the easy use of Yb 3+ ions as a sensitizing centres for enhance upconversion luminescence of Tm 3+ and efficient pumping of Yb 3+ /Tm 3+ system by semiconductor high-power laser diodes.…”

Fabrication and characterization of pedestal optical waveguides using TeO2–WO3–Bi2O3 thin film as core layer

“…A great interest in pedestal-type waveguides has emerged in integrated optics since they present favorable characteristics for confining the optical field [7] and are largely employed in the construction of microdisks for integrated laser microcavities [8]. Literature has already reported the use of pedestal structure [7][8][9].…”

“…Literature has already reported the use of pedestal structure [7][8][9]. This structure is obtained etching the lower cladding before the deposition of the core layer.…”
