Terahertz wave switch of eight-claw ring structure

Abstract

The invention discloses a terahertz wave switch of an eight-claw ring structure. The terahertz wave switch comprises a first signal input terminal, a laser input terminal, a signal output terminal, a substrate, a waveguide transmission band and an eight-claw ring structure waveguide, wherein the waveguide transmission band and the eight-claw ring structure waveguide are arranged on the substrate, and the eight-claw ring structure waveguide comprises a ring waveguide, a trigram rectangular coupled waveguide and J-shaped waveguides; the trigram rectangular coupled waveguide comprises eight rectangular coupled waveguide blocks which are arranged by taking the center of the ring waveguide as a center, and the tail ends of the eight rectangular coupled waveguide blocks are respectively coupled with one end of each of the eight J-shaped waveguides; and the other ends of the eight J-shaped waveguides are coupled with the ring waveguide, and terahertz wave signals are input through the first signal input terminal and output through the signal output terminal. The terahertz wave switch of the eight-claw ring structure provided by the invention has the advantages of simple structure, small size, low cost, convenience in manufacture and the like, and meets the requirements of application in the field of terahertz wave communication and the like.

Description

technical field [0001] The invention relates to a terahertz wave switch, in particular to a terahertz wave switch with an eight-claw ring structure. Background technique [0002] Terahertz waves refer to electromagnetic waves with a frequency of 0.1 to 10 THz and a wavelength of 30 μm to 3 mm. In the electromagnetic spectrum, they are located between microwaves and infrared light. In the field of electronics, terahertz waves are also called millimeter waves or submillimeter waves. ; In the field of optics, it is also known as far-infrared light. Terahertz waves exist widely in nature. The thermal radiation frequency of most objects at room temperature is about 6 THz. Half of the cosmic background radiation produced in the Big Bang belongs to the terahertz wave band. Although terahertz radiation is full of nature, before the mid-1980s, due to the lack of high-energy, high-efficiency, stable operation of terahertz radiation sources at room temperature and effective terahertz ...
