Modified chalcogenide glasses for optical device applications (2007)
Thesis
Hughes, M. (in press). Modified chalcogenide glasses for optical device applications. (Thesis). University of Southampton

This thesis focuses on two different, but complementary, aspects of the modification of gallium lanthanum sulphide (GLS) glasses. Firstly the addition of transition metal ions as dopants is examined and their potential for use as active optical mat...

Concentration dependence of the fluorescence decay profile in transition metal doped chalcogenide glass (2007)
Journal Article

In this paper we present the fluorescence decay profiles of vanadium and titanium doped gallium lanthanum sulphide (GLS) glass at various doping concentrations between 0.01 and 1% (molar). We demonstrate that below a critical doping concentration t... Read More about Concentration dependence of the fluorescence decay profile in transition metal doped chalcogenide glass.

Spectroscopy of vanadium (III) doped gallium lanthanum sulphide chalcogenide glass (2007)
Journal Article
chalcogenide glass. Applied Physics Letters, 90, 031108. https://doi.org/10.1063/1.2432280

Vanadiumdopedgalliumlanthanum sulphide glass (V:GLS) displays three absorption bands at 580, 730, and 1155nm identified by photoluminescence excitation measurements. Broad photoluminescence, with a full width at half maximum of ∼500nm , is observed... Read More about Spectroscopy of vanadium (III) doped gallium lanthanum sulphide chalcogenide glass.

Fabrication and characterization of femtosecond laser written waveguides in chalcogenide glass (2007)
Journal Article

The authors describe the fabrication of buried waveguides in a highly nonlinear chalcogenide glass, gallium lanthanum sulfide, using focused femtosecond laser pulses. Through optical characterization of the waveguides, they have proposed a formatio... Read More about Fabrication and characterization of femtosecond laser written waveguides in chalcogenide glass.
