Characterisation of New Planar Radiometric Detectors using Carbon Nanotube Absorbers under Development at NIST



Malcolm G. White, Nathan A. Tomlin, Christopher S. Yung, Michelle S. Stephens, Ivan Ryger, Solomon I. Woods, John H. Lehman, Igor Vayshenker


Carbon nanotube technology, in conjunction with silicon micro-fabrication techniques, has enabled us to develop planar radiometric detectors, which has led to the establishment of a new generation of primary standards. The goal is to develop compact, fast, and easy-to-use, radiometric calibration systems, spanning the wavelength spectrum from the ultraviolet to the THz region in a single detector, suitable for use with both coherent and incoherent sources, and encompassing open beam and fibre-coupled modes of operation, with utility beyond that of the laboratory environment. Work will be presented comparing scales derived from two new table- top systems, to existing radiant power and optical fibre power scales, traceable to SI.
