Abstract :
We report on terahertz frequency and power measurements based on terahertz frequency comb and a bolometer. Terahertz frequency comb and its individual modes are measured through multiheterodyne beat detection by use of a bolometer. A power spectrum of terahertz frequency comb is measured over the frequency up to 1.7 THz, and the frequency and power of the comb modes spectrally resolved are measured. Also, it is demonstrated that a single-frequency terahertz radiation can be totally characterized with this experimental scheme.
