Abstract

The invention discloses a terahertz wave polarization beam splitter connected in series with three semi-arc structures. The terahertz wave polarization beam splitter comprises a signal input end, a first signal output end, a second signal output end, a first straight waveguide, a second straight waveguide, a third straight waveguide, a fourth straight waveguide, a first semicircular waveguide structure, a second semicircular waveguide structure, a third semicircular waveguide structure, a first cladding layer and a second cladding layer, wherein the first cladding layer is uniformly and symmetrically coated at the periphery of the second straight waveguide; the second cladding layer is uniformly and symmetrically coated at the periphery of the third straight waveguide; and a signal is input from the signal input end, TE waves are output from the first signal output end and TM waves are output from the second signal output end through the asymmetric coupling functions of the first cladding layer and the second cladding layer, and polarization beam-splitting performance is obtained. The terahertz wave polarization beam splitter is simple in structure, high in beam-splitting rate, small in size, low in cost and easy to manufacture.

Description

Technical field [0001] The present invention involves a beam device, especially the Taehz wave polarizer with three semi -semi -arc structures. Background technique [0002] Tai Hez radiation is a collective name for an electromagnetic radiation in a specific band. It is located between microwave and infrared radiation in the electromagnetic spectrum. In the field of electronics, the electromagnetic waves in this frequency band are also known as millimeter waves and sub -millimeter waves; and and theIn the field of spectral science, it is also called far -infrared rays.The electromagnetic waves within the range of 0.1 ~ 10THz or the wavelength of the Taihez wave frequency are within the range of 30 μm to 3 mm.Due to the lack of high -efficiency launch sources and sensitive detectors of the tilted band, the electromagnetic radiation of this band has not been studied in depth. Microwaves and infrared radiation on both sides of the Tahez wave have been widely used in communication, ...
