Description

Technical field [0001] The invention relates to a terahertz frequency doubling circuit based on micro-nano integrated manufacturing technology, in particular to a compact terahertz power synthesis frequency doubling circuit. Background technique [0002] Terahertz (Terahertz, abbreviated THz) usually refers to electromagnetic waves with a frequency in the range of 0.1 THz to 10 THz (wavelength of 30 μm to 3 mm). 1THz (10 12 Hz) The corresponding wave number is 33.3cm -1 , The energy is 4.1meV, and the wavelength is 300μm. In terms of frequency spectrum, terahertz waves are between microwave and infrared in the electromagnetic spectrum, in the transition region from electronics to photonics, and in the transition region from macroscopic classical theory to microscopic quantum theory. In the field of electronics, terahertz waves are called submillimeter waves; in the field of optics, they are also called far-infrared rays; from the energy point of view, the energy of the terahertz...
