Abstract

The invention provides a bidirectional mechanical tuning terahertz wave modulator and a preparation method and application thereof. The terahertz wave modulator comprises a fixed control frame; the fixed control frame comprises a bottom plate, adjustable deformation is arranged on the bottom plate; the array element responds to terahertz; open holes allowing terahertz waves to pass through conveniently are formed in the positions, corresponding to the array elements, of the bottom plate. Micro-displacement mechanisms are connected to the right end and the lower end of the array element, the micro-displacement mechanisms are arranged on the bottom plate, the left end and the upper end of the array element are arranged on the bottom plate through first fixing bases, and the four ends of thearray element are kept horizontal and located on the same horizontal plane. The terahertz wave modulator and the preparation method thereof are simple, low in cost and convenient to regulate and control, and continuous stretching regulation and control can be performed in two different directions respectively or simultaneously.

Description

technical field

[0001] The present invention relates to the technical field of terahertz wave modulators, in particular to a two-way mechanically tuned terahertz wave modulator and its preparation method and application. Background technique

[0002] Terahertz waves usually refer to electromagnetic waves with a frequency between 0.1THz and 10THz (wavelength between 3mm and 30μm). Coincidence is the transition zone from the macroscopic classical theory to the microscopic quantum theory, and it is also the transition zone from the field of electronics to the field of photonics on the electromagnetic spectrum.

[0003] When terahertz waves interact with matter, many novel and peculiar physical or chemical phenomena will occur, which provides favorable conditions for its application in THz imaging, short-distance wireless communication and material characterization. THz waves will not ionize the material when propagating inside the substance; will not scatter when encountering ...
