Description
Technical Field
The invention relates to the field of optical fiber communication, in particular to a rectangular hollow optical fiber.
Background
With the vigorous development of the global internet, people put higher and higher demands on information transmission technology, thereby causing the crisis of optical transmission capacity. The hollow optical fiber is expected to become an ideal optical transmission channel, and the optical field is mainly distributed in the hollow fiber core, so that the hollow optical fiber has great advantages in the aspects of overcoming optical fiber loss, chromatic dispersion, nonlinear effect and the like.
Through years of development, hollow fibers have evolved into two types, hollow photonic bandgap fibers and antiresonant hollow fibers. The hollow Bragg fiber is a hollow photonic bandgap fiber and is composed of a hollow core region and a periodic coaxial structure cladding layer with overlapped high and low refractive index layers, the loss of the fiber is reduced along with the increase of the number of medium layers in the fiber cladding layer, and the high and low refractive index layers in the cladding layer are generally composed of solid mediums. The high refractive index difference of the two overlapping media in the Bragg fiber mirror helps to achieve a wide Low loss bandwidth [ Steven G. Johnson, et al, "Low-loss asymptotically single-mode propagation inlarge-coreOmniGuide fibers," Opt. Express, 2001, 9 (13), 748-779]. Alirezahasani et al [ alirezahasani, et al, "Porous polymer fibers for low-lossTerahertz guiding," opt. Express, 2008, 16 (9), 6340-6351 ] proposed using sub-wavelength dielectric cylinders as the bridge supports and connects dielectric layer mirrors to implement Bragg fibers, however dielectric cylinders cause the appearance of more cladding modes, and the low loss bandwidth of the fiber is limited. Negative curvature antiresonant hollow fiber [ f.yu, et al, "Low loss silica hollow core fibers for 3-4 μm spectral region," Optics Express, 2012, 20 (10), 11153-11158] can arrange the nodes as far from the core as possible, thereby reducing the impact of the nodes on fiber performance.
In the prior art, a thin-wall layer is added in a capillary of an optical fiber cladding or a capillary is used as a supporting component to increase the optical fiber cladding so as to reduce the optical fiber loss, for example, chinese patent application publication No. CN107797175a discloses a multi-resonant layer hollow anti-resonant optical fiber, which includes a low refractive index core region and a high refractive index cladding region, wherein the high refractive index cladding region includes an inner cladding region and an outer cladding region, the outer cladding region covers the inner cladding region and the core region, the inner cladding region includes a first anti-resonant layer and a second anti-resonant layer, and the first anti-resonant layer and the second anti-resonant layer surround the core region; the first antiresonant layer comprises a plurality of layers of microcapillaries, and the second antiresonant layer supports the first antiresonant layer. However, this technique increases the nodes in the cladding of the fiber, thereby causing excessive cladding modes, which need to be precisely adjusted during the fiber preparation process to avoid the effect of the cladding modes at the nodes.
Therefore, there is a need for research and development of a hollow fiber that reduces loss by adding a dielectric layer.
Disclosure of Invention
In order to solve the technical problems, a first aspect of the present invention provides a rectangular hollow fiber, where the fiber includes a cladding region with a high refractive index and a core region with a low refractive index, and the cladding region is composed of a first rectangular ring medium tube, a second rectangular ring medium tube and a third rectangular ring medium tube; the outer wall of the outermost layer medium tube of the first type rectangular ring medium tube provides a part of boundary for the fiber core, the inner wall of the innermost layer medium tube of the second type rectangular ring medium tube provides another part of boundary for the fiber core, and the third type rectangular ring medium tube is distributed on the outermost layer; the first type rectangular ring medium pipe, the second type rectangular ring medium pipe and the third type rectangular ring medium pipe are nested in sequence from inside to outside; and the area surrounded by the outer wall of the outermost medium tube of the first rectangular ring medium tube and the inner wall of the innermost medium tube of the second rectangular ring medium tube is the fiber core area.
Wherein the pipe wall of one direction of the first type rectangular ring medium pipe is located on the pipe wall of the third type rectangular ring medium pipe.
Wherein the pipe wall of one direction of the second type rectangular ring medium pipe is located on the pipe wall of the third type rectangular ring medium pipe.
Wherein, the pipe wall of two directions of the second class rectangular ring medium pipe falls on the pipe wall of the third class rectangular ring medium pipe.
The cross sections of the first type rectangular ring medium pipe, the second type rectangular ring medium pipe and the third type rectangular ring medium pipe are rectangular.
Wherein the material of the cladding region is any one of silicon dioxide, soft glass or plastic.
Wherein the core region is filled with one or two or more gases.
Wherein the core region is a vacuum.
Wherein the number of the first type of rectangular ring medium pipes is 2, 3, 4, 5, 6, 7, 8, 9 and 10.

The invention has the beneficial effects that:
according to the rectangular hollow optical fiber provided by the invention, the optical fiber modes are only distributed in the hollow fiber core, so that the material absorption loss of the optical fiber can be effectively reduced, and the damage threshold of the optical fiber is improved. The optical fiber can increase the reflecting layer of the light by increasing the number of layers of the first-type and second-type rectangular ring medium pipes, thereby increasing the binding capacity of the light and reducing the mode leakage loss. The distance between the fiber node and the fiber core can be adjusted by increasing the size of the first rectangular medium tube, and the coupling between the fiber core mode and the cladding mode at the node can be reduced by increasing the distance, so that the influence of the cladding mode at the node on the fiber core mode is reduced. The high-order mode in the fiber core can be coupled with the cladding mode by adjusting the interval between the layers in the fiber cladding, and the loss of the high-order mode of the fiber core is increased, so that single-mode transmission is realized. The fiber core is rectangular, so that symmetry is broken conveniently, and the high-birefringence hollow fiber is realized.
