Embodiment Construction

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] The base material used in a kind of tellurate group velocity matching photonic crystal fiber designed by the present invention is 60TeO 2 -20PbO-20PbCl 2 (TLX), using the three-term Sellmeier equation to calculate its refractive index:

[0028] no 2 (λ)=1+B 1 lambda 2 / (λ 2 -C 1 )+B 2 lambda 2 / (λ 2 -C 2 )+B 3 lambda 2 / (λ 2 -C 3 )

[0029] where λ is the wavelength in μm, B i (i=1,2,3) and C i (i=1,2,3) are coefficients, and the six coefficients corresponding to TLX glass are: B 1 = 1.212, B 2 = 2.157, B 3 = 0.1891, C 1 =6.068×10- 2 , C 2 =7.068×10- 4 , C 3 = 45.19. The refractive index of TLX is very high, and its refractive index varies with wavelength as shown in figure 1 shown. Tel...

Abstract

The invention relates to a tellurate group velocity matching photonic crystal fiber. The tellurate group velocity matching photonic crystal fiber is provided with a fiber core and a cladding which areboth made of substrate materials 60TeO2-20PbO-20PbC12; a plurality of air holes which are arranged in parallel along a fiber axis are formed in the substrate materials; on any cross section of the fiber: the plurality of air holes are distributed in a multi-layer manner along the axle center of the fiber; the air holes of each layer can form a regular hexagon; the distance between the hole centers of any two adjacent air hoses is that P=4 mu m, the diameter d1 of each air hole in the innermost layer is the same, and the range of d1 is 3.0-3.7 mu m, and the diameter of other air holes is 3 mum, or the distance between the hole centers of any two adjacent air hoses is the same, and P is 3.80-4.15 mu m, and the diameter d1 of the innermost layer is 3.3 mu m, and the diameter d of the otherair holes is 3 mu m; and the substrate materials enclosed by the circles which are formed among the hole centers of the air holes of the innermost layer form the fiber core, and other substrate materials and air holes form the cladding. The tellurate group velocity matching photonic crystal fiber can realize group velocity matching of any wavelength between the 1.55 mu m wave band and the 2 mu m wave band, is simple in structure, is easy to manufacture, and is efficiency in cross phase modulation.

Description

technical field [0001] The invention relates to the field of optical fibers, and more specifically relates to a tellurate group velocity matching photonic crystal optical fiber. Background technique [0002] With the development of communication technology and people's strong demand for information interaction, all-optical communication network technology has undoubtedly become the main force of global communication. The rapid development of optical communication network has made its capacity increase exponentially in the past few decades, and there have been many breakthroughs in technology, including low-loss single-mode transmission fiber, erbium-doped fiber amplifier, wavelength division multiplexing, etc. For long-distance and high-capacity transmission, most work has been carried out in the C-band communication window (1530nm ~ 1565nm), where the optical fiber transmission loss is the smallest, and low noise amplification can be obtained, and advanced modulation format...
