Abstract: An optically active glass and an optical fiber comprising such glass, having reduced photodarkening properties are provided. The optically active glass is mainly composed of silica representing from about 50 to 98 mol % of the glass. It also includes at least one active ion, such as a rear-earth ion, which induces a photodarkening effect in optical properties of the glass. Moreover, the glass includes an effective amount of phosphorus oxide providing the photodarkening reducing effect, preferably in an amount of from about 1 to 30 mol %. A method for reducing a photodarkening effect in optical properties of an optically active glass including the step of introducing phosphorus oxide to the glass is also provided.

Abstract: A light-emitting device is provided which includes a gain medium having an optically-active phosphosilicate glass, wherein the phosphosilicate glass includes at least one active ion dopant and from about 1 to 30 mol % of phosphorus oxide. The phosphorous oxide may be present in an effective amount for reducing any photodarkening effect and increasing the saturation energy of the system. The active ion dopant may be a rare earth dopant. The light-emitting device may include an optical waveguide, the optical waveguide including the gain medium. The optical waveguide may have a core and at least one cladding, and the gain medium having the phosphosilicate glass may be found in the core and/or in one of the cladding

Abstract: The polarization maintaining optical fiber, or preform therefore, can be of the panda type with a pedestal based on a multi-component silica glass doped with a thermal-expansion-coefficient-reducing dopant which can counteracts the thermal-expansion-coefficient-increasing side-effect of the refractive index-increasing dopant, such that when the preform is drilled to make the stress member channel in a heterogeneous region having both a pedestal portion and a cladding portion, the thermal expansion coefficients are sufficiently close to manage damage which could otherwise be caused by uneven thermal expansion caused by drilling heat.
