Terahertz quasi-optical power combining and amplification device

Abstract

The invention relates to a terahertz quasi-optical power combining and amplifying device. Including microwave transmitting horn antenna, main parabolic reflector group A, sub-parabolic reflector group A', microwave amplification array chip, terahertz frequency doubling array chip, main parabolic reflector group B, sub-parabolic reflector group B' and super-external Difference terahertz quasi-optical receiver. The main parabolic mirror group A and the secondary parabolic mirror group A' are used to convert the spherical electromagnetic wave signal fed into the space into a plane wave signal and transmit it to the microwave amplification array chip to realize amplification and output. The amplified microwave signal is transmitted to the terahertz frequency doubling array chip for frequency doubling and output. The frequency-multiplied terahertz signal passes through the structure of the main parabolic mirror group B and the sub-parabolic mirror group B′, and synthesizes a high-power signal in space in the form of beam focusing, and is received by the terahertz quasi-optical receiver. The quasi-optical power combining structure can be used to output high-power terahertz signals, and the structure is simple and the debugging is convenient.

Description

technical field [0001] The invention relates to a terahertz quasi-optical power combining and amplifying device, specifically, a high-efficiency spatial power combining and amplifying technology field applicable to the terahertz frequency band. Background technique [0002] With the development of science and technology, terahertz frequency band systems are more and more used in microwave remote sensing, medical imaging, radar, space communication and other fields due to their large transmission signal capacity, compact structure and higher resolution. However, the development of terahertz technology still faces many difficulties. First, as the frequency continues to rise, various transmission lines such as waveguides and microstrips have disadvantages such as reduced size, increased loss, reduced power, difficult processing, and high cost. Second, the optical properties of terahertz electromagnetic waves are gradually emerging, and the traditional full-wave electromagnetic...
