An apparatus, method and thin-film structure for producing a blackbody spectrum is disclosed. A first layer of the apparatus is configured to generate heat in response to an applied voltage. A second layer is configured to emit the blackbody radiation spectrum in response to the heat from the first layer. A thermal spreading layer is disposed between the first layer and the second layer. The thermal spreading layer includes a graphene sheet for reducing a spatial variation of the heat in a plane of the thermal spreading layer.

A thermal shunt comprising flexible graphite fibers for removing heat from components coupled thereto and providing mechanical isolation. The thermal shunt comprises a plurality of stacked layers of graphite fibers secured together at opposite ends to form rigid sections at the respective opposite ends that provide for thermal coupling. Portions of the graphite fibers between the rigid sections are flexible and provide mechanical isolation between components to which the thermal shunt is coupled.
