Design of a Cryogenic Terahertz Fourier Transform Spectrometer

Abstract:

With the rapid development of the terahertz technique, many new devices are developed in recent years, and most of them need cryogenic environment. To evaluate the characteristics of these devices at low temperature, a cryogenic terahertz Fourier transform spectrometer system (THz-FTS) is designed and developed. With the different combinations of terahertz sources and detectors, this THz-FTS system can test the frequency response of the detectors, the emission spectrum of the sources, and the transmittance of material in the cryogenic environment at terahertz frequency range and also the basic electrical characteristics of the devices. The cryogenic THz-FTS system is designed multi-functional, low noise and compacted to test both the optical and electrical characteristics of the terahertz devices at low temperature.
