Abstract
The utility model discloses a terahertz wave transmission fiber, it includes material layer (3), air bed (2) and outer loop (1), circles in outer loop (1) to inlay to be equipped with many wires of at least round (4), arrange in turn material layer (3) and air bed (2), it is inside that outer loop (1) is fixed in in material layer (2), material layer (3) number of piles N > 2. This optic fibre adopts the wire to reflect terahertz wave, reduces the loss, and material layer and outer loop comprise the same material, and its refracting index is higher than the refracting index of air bed to the equivalent refracting index of optic fibre is greater than the refracting index of the air in its outside.
Description
Technical field
The utility model belongs to special fiber field, relates to a kind of THz wave Transmission Fibers.
Background technology
THz wave is the electromagnetic wave of frequency within the scope of 0.1 ~ 10THz.Owing to lacking the method that effective THz wave produces and detects, Terahertz Technology is in space state always for a long time, becomes the last frequency range needing exploitation in electromagnetic spectrum.THz wave technology is at safety guard, and chemical, biological, medical diagnosis, there is extraordinary application prospect the aspects such as astrophysics.Terahertz Technology mainly comprises: the generation (THz source) of THz wave, three aspects such as the transmission (Hz optical fiber) of THz wave and the detection (terahertz detector) of THz wave.In recent years, along with various countries are in the input energetically in this field, Terahertz Technology has achieved many progress in the generation and detection etc. of THz wave.But have higher loss at terahertz wave band due to most of material, therefore THz wave also lacks suitable low-loss transmission optical fiber at present.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of THz wave Transmission Fibers is provided, this optical fiber adopts tinsel to reflect THz wave, reduce the wastage, material layer is made up of identical material with outer shroud, its refractive index is higher than the refractive index of air layer, thus the equivalent refractive index of optical fiber is greater than the refractive index of the air outside it.
The purpose of this utility model is achieved through the following technical solutions: a kind of THz wave Transmission Fibers, it comprises material layer, air layer and outer shroud, outer shroud inner ring is embedded with the many one metal wires of at least one circle, the alternately arrangement of material layer and air layer, material layer is fixed on outer shroud inside, material layer number of plies N > 2.
When the number of turns that described tinsel is formed is multi-turn, the tinsel radical of each circle is equal.
Described tinsel is filamentary silver, aluminium wire, spun gold, copper wire, iron wire, Mo silk, nickel wire, tin silk, tungsten filament or titanium silk.
Described material layer is identical with outer ring material, is the organic polymer comprising teflon, tygon, polycarbonate or polystyrene.
The beneficial effects of the utility model are: the utility model provides a kind of THz wave Transmission Fibers, this optical fiber adopts tinsel to reflect THz wave, reduce the wastage, material layer is made up of identical material with outer shroud, its refractive index is higher than the refractive index of air layer, thus the equivalent refractive index of optical fiber is greater than the refractive index of the air outside it.
Accompanying drawing explanation
Fig. 1 is light structural drawing;
In figure, 1-outer shroud, 2-air layer, 3-material layer, 4-tinsel, 5-, 6-, 7-, 8-, 9-, 10-, 11-, 12-.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of THz wave Transmission Fibers, it comprises material layer 3, air layer 2 and outer shroud 1, outer shroud 1 inner ring is embedded with the many one metal wires 4 of at least one circle, the alternately arrangement of material layer 3 and air layer 2, it is inner that material layer 2 is fixed on outer shroud (1), material layer 3 number of plies N > 2.
When the number of turns that described tinsel 4 is formed is multi-turn, the tinsel 4 of each circle) radical is equal.
Described tinsel 4 is filamentary silver, aluminium wire, spun gold, copper wire, iron wire, Mo silk, nickel wire, tin silk, tungsten filament or titanium silk.
Described material layer 3 is identical with outer shroud 1 material, is the organic polymer comprising teflon, tygon, polycarbonate or polystyrene.
