1.2 - Superconducting Bolometer for Terahertz Detection

M. Kehrt, C. Monte, J. Beyer & J. Hollandt
Over decades the spectral range from 0.1 THz to 3 THz (the spectral range of far-infrared (FIR) or THz radiation) was covered by astronomic research. In the last years THz radiation became a growing field of interest in laboratory measurements, industry and homeland security. Supporting these efforts we are developing a composite bolometer for 4.2 K operation that addresses the special requirements of Fourier transform spectroscopy, namely high and uniform absorption over the whole spectral...
