Method and system used for improving Terahertz wave power by using power synthesis and based on phase synchronization

Abstract

The invention discloses a method and system used for improving Terahertz wave power by using power synthesis and based on phase synchronization. The system comprises a digital control circuit, phase-locked loop frequency synthesizing circuits, a frequency doubling filtering circuit, a power amplification circuit, an avalanche pipe high order frequency doubling structure and a power synthesizing module. The four phase-locked loop frequency synthesizing circuits are regulated and controlled through the digital control circuit, and four branches of signals correct in frequency and adjustable in phase are generated and changed into excitation signals meeting requirements through the frequency doubling filtering circuit and the power amplification circuit. The excitation signals are subjected to high order frequency doubling through an avalanche pipe to obtain the expected TeraHertz wave frequency, by adjusting four branches of excitation signal phases, the four branches of TeraHertz wave signals can achieve phase synchronization, four branches of TeraHertz waves synchronous in phases are subjected to power synthesis through the power synthesizing module, and a purpose of improving the Terahertz wave power is achieved.

Description

technical field [0001] The present invention relates to a method and a system for terahertz waves, in particular to a method and a system for increasing the power of terahertz waves by using power synthesis in phase synchronization. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with a frequency in the range of 0.1-10THz. Microwave millimeter waves and infrared radiation on both sides of THz waves are well developed and widely used. Terahertz occupies a very special place in the electromagnetic spectrum. Terahertz waves are not only the transition zone from macroscopic classical theory to microscopic quantum theory, but also the transition zone from electronics to photonics, known as the "THz gap" of the electromagnetic spectrum. Terahertz science and technology is an emerging technology in the past 20 years. Although human beings have made great progress in the research and understanding of THz, THz technology not only has important rese...
