The application of the microwave approach to the developing of the terahertz (THz) frequency range allowed producing the set of precise methods and devices for various applications. The midpoint of the development was the using of the mixers and multipliers on the quantum semiconductor superlattices which allow more effective signal transformation in comparison with usually used devices based on Schottky...
The creation opportunity of a subTHz range spectrometer for precision, non-stationary spectroscopy (with registration of a signal in time area) is shown on the basis of solid-state sources of radiation and multiplication of frequency with use of quantum semiconductor superlattices
