The advantages of using high precision, time-domain spectroscopy in THz frequency range are presented. The advantages of application of solid-state sources (synthesizers) of millimeter wavelength with PLL of reference generator and frequency multipliers on quantum semiconductor structures are shown. The results of measurements of spectral distribution after multiplier are presented.
In the report results of optimization of the planar diodes based on GaAs/AlAs superlattices for use in devices of THz range of frequencies are considered. The purpose of optimization was reduction of value of series resistance of losses Rs and parasitic capacity Cpar of a substrate of the diode. The Rk contains have been designed. It is found, that at the area of active region of the diode less 2times10...
Frequency multiplication of phase locked, high power backward wave oscillators (BWO) permitted to record high accuracy spectra of ND 2 H up to frequencies of 2.6THz. Novel superlattice (SL) devices were used as key-element to generate higher order harmonics for the first time in spectroscopic applications. In total, 240 measured ground state transitions of the pure rotation and inversion–rotation...
