A terahertz quasi-optical power combining and amplifying device

Abstract

The invention relates to a terahertz quasi-optical power combining and amplifying device and is applied to power combination and amplification of a terahertz frequency band. The device comprises a microwave transmission horn antenna, a dielectric lens A, a microwave amplification array chip, a terahertz frequency-doubling array chip, a dielectric lens B and a terahertz horn reception antenna. According to the focusing effect of the dielectric lens A, spherical electromagnetic wave signals input by the microwave transmission horn antenna are converted into plane wave signals which are transmitted to the microwave amplification array chip to realize amplification and output. Amplified microwave signals are transmitted to the terahertz frequency-doubling array chip to realize frequency doubling and output. The frequency-doubling terahertz signals combine into high-power signals through the dielectric lens B in the form of quasi-optical wave beams, thereby realizing coupling and matching with the terahertz horn reception antenna. The high-power terahertz signals can be outputted by adopting a quasi-optical power combining structure, thus the terahertz quasi-optical power combining and amplifying device is simple in structure and convenient to debug.

[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, in the terahertz frequency band, various transmission lines such as waveguides and microstrips have disadvantages such as smaller size, increased loss, reduced power, difficult processing, and high cost. Second, the optical properties of terahertz electromagnetic waves are gradually emerging, and th...
