Abstract

The invention discloses a strip structure-based electric control terahertz wave switch, which comprises a substrate layer, a silicon dioxide layer, a molybdenum disulfide film, a first strip region, a left rectangular strip, a second strip region, a right rectangular strip and a third strip region, wherein the molybdenum disulfide film is provided with the first strip region, the left rectangular strip, the second strip region, the right rectangular strip and the third strip region; the first strip region, the left rectangular strip, the second strip region, the right rectangular strip and the third strip region are sequentially arranged on the molybdenum disulfide film from left to right; a terahertz signal vertically enters from the upper part of the second strip region and sequentially passes through the molybdenum disulfide film, the silicon dioxide layer and the substrate layer for vertical output. On / off of the terahertz signal is achieved through adjusting offset DC voltage applied between the molybdenum disulfide film and the substrate layer and adjusting an effective dielectric constant of the molybdenum disulfide film. The strip structure-based electric control terahertz wave switch has the advantages of being simple and compact in structure, small in size, fast in response and simple in design principle.

Description

technical field [0001] The invention relates to a terahertz wave switch, in particular to an electronically controlled terahertz wave switch based on a strip structure. Background technique [0002] In recent years, terahertz technology, which is in the transitional region from macroscopic electronics to microscopic electronics, is a new technology developed in the late 1980s. The unique frequency range of terahertz waves (located between the microwave frequency band and the optical frequency band) covers the molecular vibration and rotation spectra of most macromolecular substances, so most macromolecular substances in the terahertz frequency band regardless of their absorption, reflection or emission spectra have Obvious fingerprint characteristics, which is not available in microwave. The rapid progress of terahertz wave radiation sources and detection methods has promoted the quiet rise of related device functions. Therefore, the research on terahertz technology and te...
