  • Patent number: 10527500
    Abstract: A thin-film device for generating a blackbody spectrum is disclosed. The device includes first layer configured to generate heat in response to an applied voltage and a second layer configured to generate the blackbody radiation spectrum in response to the heat from the first layer. A thermocouple is disposed between the first layer and the second layer for measuring a temperature at the second layer. The thermocouple measures temperature at the second layer in order to control temperature at the second layer. The thermocouple can be a copper-carbon nanotube thermocouple.

  • Patent number: 9606311
    Abstract: A method includes obtaining a substrate having at least one exposed metal surface. The method also includes electro-depositing metal onto the at least one exposed metal surface of the substrate and around at least a portion of an optical fiber to secure the optical fiber to the substrate. The substrate and the electro-deposited metal are configured to remove heat from the optical fiber. The method could further include electro-depositing metal around a sacrificial material and removing the sacrificial material to form at least one cooling channel through the electro-deposited metal. The optical fiber could include a polymer coating, where a portion of the polymer coating is removed at an end of the optical fiber. The substrate and the electro-deposited metal could be faceted at an input of the optical fiber and at an output of the optical fiber. The optical fiber could have a coiled arrangement on the substrate.
