Abstract

The invention discloses a light-operated terahertz wave 3-bit encoder and an encoding method. The light-operated terahertz wave 3-bit encoder comprises a substrate layer, a metal layer, a positioningmark and an encoding structure. The metal layer and the positioning mark cover the upper surface of the substrate layer. The coding structure is etched on the metal layer. The encoding structure is composed of a plurality of double-circle structures and a plurality of square structures. All the double-circle structures are arranged periodically, all the square structures are arranged periodically,and a double-circle array formed by all the double-circle structures and a square array formed by all the square structures are arranged in a staggered mode. Terahertz waves can be controlled, codingof three bits, namely eight states, can be achieved, and compared with a previous coding structure, the coding capacity and the information transmission capacity are greatly improved. Resonance responses of three frequency points can be controlled at the same time, the acting frequency band is wider, and the coding frequency range is wider. The method has the characteristics of simple process, simple structure and high coding rate.

Description

technical field [0001] The invention relates to the technical field of terahertz communication, in particular to an optically controlled terahertz wave 3-bit encoder and an encoding method. Background technique [0002] Terahertz refers to electromagnetic waves with a frequency between 0.1THz and 10THz, which is between infrared and microwave in the spectrum, and is a frequency band that has not yet been fully developed. Its spectrum resources can reach tens of GHz, which can meet the communication requirements of ultra-high transmission rate up to Tbit / s level. At present, the United States, Europe, Japan and other countries have begun to accelerate the research and development of 6G technology, and terahertz communication technology is considered to be one of the key technologies of 6G communication. However, the lack and maturity of related terahertz devices restrict the development of terahertz communication technology. Therefore, research on devices related to teraher...
