  • Patent number: 9945985
    Abstract: There is provided a method for making an optical element having a textured surface. The method comprises the steps of: a) providing a plurality of primary optical fiber segments, each primary fiber segment comprising one or more cores; b) bundling the primary fiber segments into an assembly with the cores of said primary fiber segments extending parallely; c) transforming the assembly into a secondary structure comprising the parallely extending cores; and d) etching a surface of the secondary structure according to an etch profile of said secondary structure, the etch profile being defined by the parallely extending cores, thereby forming the textured surface of the optical element. An optical element having a textured surface is also provided.

  • Patent number: 8542971
    Abstract: A package for dissipating heat power and/or optical power from an optical fiber component of a device is provided. The package includes a heat sink packaging receptacle for accommodating the optical fiber component having a cavity for receiving a temperature sensitive portion of the optical fiber component. According to one aspect, the package may include a power-dissipative material for dissipating heat power or optical power, the power-dissipative material extending within the cavity and surrounding the temperature-sensitive portion of the optical fiber component. According to another aspect, the package may include at least one channel extending between the cavity and an end of the heat sink packaging receptacle, the channel being in intimate contact with the cladding of the optical fiber component for dissipating heat power and/or optical power from the optical fiber component.

  • Publication number: 20130071082
    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.

  • Patent number: 8270445
    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.

  • Patent number: 8055115
    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.

  • Patent number: 7046902
    Abstract: A large mode field diameter optical fiber is disclosed. It is a single mode optical fiber which has a core and a cladding. The core of this fiber has two regions, an inner core region and an outer core region which has a refractive index lower than that of the inner core region. The inner core region is doped with a rare-earth element, such as Er2O3, and a co-dopant, such as Al2O3, and the outer core region is doped with a dopant such as GeO2. The types and amounts of the dopants and co-dopants are adjusted to obtain a fiber with a mode field diameter greater than 5.5 ?m at a wavelength of 1550 nm.
