[0025] Example
[0026] figure 1 It is a schematic diagram showing a structural cross section of a ginkgo apripficular cladding of a ginkgo apripficker.
[0027] In the present embodiment, a ginkgo biloba-shaped cladding flyfact fiber, such as figure 1 As shown, the fiber optic outer sleeve 1 is sequentially sequentially internally, the ginkgo biloba-shaped cladding tube 2, the air core 3.
[0028] The fiber optic outer sleeve 1 is the outermost layer of the empty core anti-resonant fiber, and the ginkgo biloba-shaped cladding tube 2 and the air core 3 are wrapped inside.
[0029] Ginkgo biloba-shaped cladding tube is typically made of silica and having a thickness T, which should follow the principle of the anti-resonant reflection waveguide (Arrow) principle, that is:
[0030]
[0031] Among them, λ is designed for wavelength, n 1 Indicates the refractive index of the ginkgo leaf shape cladding tube material, N 0 Indicates the refractive index of the air, m is positive intege...
