Embodiment 1

[0037] 1. Light source coupling: Take a section of one-dimensional Airy optical fiber, remove and cut the coating layer of one end of the optical fiber, and then align and weld it with the single-mode optical fiber 11 with the light source pigtail, such as Figure 13 shown;

[0038] 2. Encapsulation protection: adjust the quartz tube with an inner diameter larger than the standard optical fiber or one-dimensional Airy optical fiber to the solder joint 12 in the figure, and then use CO at both ends of the quartz tube 2 The laser is heated, welded and sealed, or encapsulated and cured with epoxy resin, and then secondly coated to complete the overall protection;

[0039] 3. Airy beam generation: the other end of the one-dimensional Airy fiber (as the beam exit end) fiber coating layer is removed and cut, input laser light 13, and the light field 5 at the exit end of the one-dimensional Airy fiber is observed. If the Airy distribution is not satisfied, then Continue cutting or g...

Embodiment 2

[0041] 1. Light source coupling: take a section of multi-core optical fiber 14 corresponding to the Airy fiber whose core is non-intersecting with multiple sets of one-dimensional array cores, such as Figure 14 As shown, remove and cut the coating layer of the optical fiber at one end, then align and weld it with the single-mode optical fiber 11 with the light source pigtail. Figure 14 The shown solder joint 15 is heated to a softened state, then tapered, and the optical power is monitored until the optical power coupled to the multi-core optical fiber reaches the maximum;

[0042] 2. Encapsulation protection 1: Adjust the quartz tube whose inner diameter is larger than the multi-core optical fiber or single-mode optical fiber to Figure 15 shown at the cone coupling region 16, and then at both ends of the quartz tube with CO 2 The laser is heated and welded to seal, or encapsulated and cured with epoxy resin;

[0043] 3. Coupling connection: Remove and cut the coating lay...

Embodiment 3

[0047] The one-dimensional Airy fiber in embodiment 1 and embodiment 2 can be replaced by two-dimensional Airy fiber, as Figure 16 and Figure 17 .

Abstract

The invention provides a multicore Airy optical fiber based on arrays, which comprises a coating layer, a covering layer and a group or multigroup of array cores, wherein spatial arrangement of each group of array cores of the optical fiber satisfies or approximately satisfies an Airy function; the Airy optical fiber in a certain length always exists, when a Gauss beam is input to one end of the optical fiber, through optical coupling between fiber cores, luminous intensity distribution of an outgoing light beam of each group of array cores at the other end of the optical fiber satisfies or approximately satisfies that of an Airy light beam. According to the multicore Airy optical fiber based on the arrays, the outgoing light beam of the optical fiber end inherits or partially inherits three major characteristics of the Airy beams, and namely, the light beam has capacities of horizontal acceleration, no diffraction and self-cure; and the multicore Airy optical fiber wholly has the characteristics of small structure, flexible operation, stable system, strong anti-interference capacity and the like, and can be used for light beam generation, particle control, sensing application and the like.

Description

(1) Technical field [0001] The present invention relates to an optical fiber, preferably for use in beam generation, particle manipulation, sensing applications, etc. using optical fibers. (2) Background technology [0002] A light wave that remains unchanged during propagation is considered a non-diffraction beam, and the most typical example of a non-diffraction wave is a Bessel beam. In 1979, M.V.Berry et al. (Am.J.Phys., 1979, 47(3): 246-267) theoretically introduced the solution of the Schrödinger equation with a diffraction-free Airy wave packet in the context of quantum science. Has the characteristic of free acceleration. In 2007, Georgios A. Siviloglou et al. (Opt.lett., 2007, 32(8): 979-981) first studied the accelerated Airy beam with limited energy, and observed the experimental results of the Airy laser beam for the first time (Frontiers in Optics, OSA , 2007.PDP_B3), the experiment verified that the Airy laser beam has unusual characteristics and can maintain...
