Abstract
Carbon nanotube technology, in conjunction with silicon micro-fabrication techniques, has enabled us to develop planar radiometric detectors, which is leading to the establishment of a new generation of primary standards at NIST. We will discuss the application of this technology to the development of this new generation of chip detectors [1,2]. The goal is to develop compact, fast, and easy-to-use calibration systems, spanning the wavelength spectrum from the ultraviolet to the THz region [3,4] 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.
Recent work to enhance the absorptivity of nanotube arrays, using post-growth treatments, and the characterization of noise in temperature sensing thermistors will be presented [5].
Finally, work comparing scales, derived from two new table-top systems, to existing radiant power and optical fibre power scales traceable to SI will be presented.
