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: 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.
