Frequency-selective high-T/sub c/ Josephson detectors have been fabricated and characterized. A spectral range from 15 GHz to 4.3 THz has been demonstrated for these detectors. A power dynamic range of 50 dB and a noise equivalent power of 10/sup -14/ W/Hz/sup 1/2/ have been realized. A spectral resolution /spl delta/f/f 10/sup -3/ has been achieved in the terahertz range. As an alternative to Fourier-transform spectroscopy, fast Hilbert-transform spectroscopy, based on these detectors, have been applied for various CW and pulsed terahertz sources.
