Abstract: An optical fibre amplifier, laser or superluminescent source, consisting of a chalcogenide glass matrix hosting trivalent rare earth ions and which is doped with oxide in the form of a metallic oxide. The device utilizes the properties of the added oxide to improve the fabrication and efficiency of optical waveguide sources, in particular for applications around 1.3 mu m. Specifically, the oxide broadens the wavelenght range for pump absorption, broadens the wavelength range for light emission, increases the device efficiency through a change in lifetime of certain laser levels and modifies properties of the glass to prevent crystallization during fibre fabrication. The device exploits the intentional addition of oxide to improve amplifier, laser, glass and fibre properties.

Abstract: Microstructured optical fibre is fabricated using extrusion. The main design of optical fibre has a core suspended in an outer wall by a plurality of struts. A specially designed extruder die is used which comprises a central feed channel, flow diversion channels arranged to divert material radially outwards into a welding chamber formed within the die, a core forming conduit arranged to receive material by direct onward passage from the central feed channel, and a nozzle having an outer part in flow communication with the welding chamber and an inner part in flow communication with the core forming conduit, to respectively define an outer wall and core of the preform. With this design a relatively thick outer wall can be combined with thin struts (to ensure extinction of the optical mode field) and a core of any desired diameter or other thickness dimension in the case of non-circular cores. As well as glass, the extrusion process is suitable for use with polymers. The microstructured optical fibre is considered to have many potential device applications, in particular for non-linear devices, lasers and amplifiers.

Abstract: A new class of phase change materials has been discovered based on compounds of: Ga; lanthanide; and chalcogenide. This includes compounds of Ga, La, and S (GLS) as well as related compounds in which there is substitution of S with O, Se and/or Te. Moreover, La can be substituted with other lanthanide series elements. It has been demonstrated that this class of materials exhibit low energy switching. For example, the GLS material can provide an optical recording medium with erasability 3-5 dB greater than the erasability of GeSbTe (GST) material which is the standard material for phase change memories.

Abstract: The invention relates to synthesis of germanium sulphide glasses and optical devices formed therefrom. In a chemical vapour deposition process, germanium tetrachloride is reacted with hydrogen sulphide at temperatures in the range 450­-700°C to form germanium sulphide. Lower temperatures within this range of 450-­550°C directly produce a glass, whereas higher temperatures within the range of 600-700°C produce a crystalline powder which can then be reduced to a glass by subsequent melting and annealing. The reaction is preferably carried out at atmospheric pressure or slightly higher. Thin films and bulk glasses suitable for optical waveguides can be formed directly in one processing step as can powders and microspheres. The materials synthesised are of a high purity with low oxide impurities and only trace levels of transition metal ions.

Abstract: Halide-containing gallium lanthanum sulphide glasses can transmit far into the infrared region of the electromagnetic radiation spectrum due to their low maximum phonon energy. Moreover, they present better UV and/or visible transmission and more importantly, some also exhibit improved glass thermal stability, when compared to those of respective non-halide containing pure gallium lanthanum sulphide glasses. These glasses are well suited for serving as hosts for active materials in making optical waveguide devices such as waveguide (either fibre or planar) lasers, optical amplifiers and superfluorescent sources. In particular, when doped with rare-earth ion such as Pr or Dy , they form the core of a waveguide as an efficient optical amplifier operating in the second telecommunication window at a wavelength around 1.3 mu m.

Abstract: The core of a low phonon energy glass optical fibre is doped with trivalent Dysprosium ions (Dy ) for application as an efficient optical fibre amplifier operating around 1.3 mu m. The device utilises the transition H9/2- F11/2 to H15/2. The low phonon energy (high quantum efficiency) glasses include mixed halides, chalcogenides and chalcohalides. Improvements in efficiency can be achieved by co-doping of the fibre core with Eu and/or Tb ions.
