Abstract

The invention relates to a magnetic field-regulated terahertz wave modulator and a manufacturing method thereof. The modulator is characterized by comprising a fixing bracket, two fixed magnetic fieldadjusting boxes and a plug-in Ni nanowire array lens, wherein the fixing bracket comprises two brackets, a sleeve and four horizontal support rods; the sleeve is welded to the tops of the two brackets; two pairs of holes are symmetrically formed in the top and the bottom of the sleeve; the four horizontal support rods are inserted into the holes respectively and are fixed by welding; an opening is disposed in a middle portion of the sleeve between the two pairs of horizontal support rods; the plug-in Ni nanowire array lens is rotatably inserted into the opening; each of the horizontal supportrod is provided with external threads on the end portion away from the sleeve; and the two fixed magnetic field adjusting boxes are slidably disposed on the external threads on the two pairs of horizontal support rods on both sides of the sleeve respectively, and are fixed by bolts. The magnetic field-regulated terahertz wave modulator can be widely applied to the field of terahertz wave modulation.

Description

technical field [0001] The invention relates to the field of terahertz wave modulation, in particular to a magnetic field control terahertz wave modulator and a manufacturing method thereof. Background technique [0002] Terahertz waves are generally defined as electromagnetic waves with frequencies ranging from 0.1THz to 10THz, which are between microwaves and infrared light, and whose wavelengths range from 30 microns to 3 mm. Compared with visible light and microwave, the terahertz wave band is an electromagnetic wave band that has not yet been fully developed. Compared with other wavelength electromagnetic waves, it has many unique properties. Its main features are: (1) Transient; (2) Penetrating; ( 3) low energy; (4) coherence; (5) broadband; (6) spectral resolution and so on. Because terahertz waves have the above characteristics, and polar molecules such as water molecules and ammonia molecules have strong absorption to terahertz waves, terahertz spectroscopy technol...
