چکیده
Simple analytical formulas for micro-bending and surface scattering loss in Hollow-Core Tube Lattice Fibers are here proposed numerically validated. They can also be applied to other fibers with similar core-cladding interfaces such as Hybrid cladding Kagome-Tubular, Nested Tubes, Kagome fibers. Scaling laws both mechanisms given discussed.

Holey Fibers for Low Bending Loss
Recently, broadband-access network has spread out rapidly, and Fiber-To-The-Home (FTTH) has showed a stable growth. Nevertheless, for the prevalence of additional FTTH, the so-called 'last one mile problem', which entails a huge cost for constructing optical fiber networks to end-users, has to be solved. To this end, it is necessary to improve economical efficiency of the products for network a...
متن کاملHollow antiresonant fibers with low bending loss.
We first use numerical simulations to show that bending losses of hollow antiresonant fibers are a strong function of their geometrical structure. We then demonstrate this by fabricating a hollow antiresonant fiber which presents a bending loss as low as 0.25 dB/turn at a wavelength of 3.35 μm and a bend radius of 2.5 cm. This fiber has a relatively low attenuation (<200 dB/km) over 600 nm mid-...
متن کاملLow-loss Bending-insensitive Micro-structured optical fiber for FTTH
In this sample paper, we describe and provide a novel Microstructured optical fiber for FTTH, which has 12 holes in its cladding. The fiber has very good bending properties. The bending losses of the novel Micro-structured fibers at the conditions of 2mm bendingradius are less than 0.1 dB at 1550 nm wavelength. The typical PMD of the novel Microstructure fibers are 0.062ps/km1/2.The splice loss...
متن کاملEffect of Cooling on Bending Angle and Microstructure in Laser Tube Bending with Circumferential Scanning
Laser tube bending is a flexible forming process. Two irradiation methods of axial and circumferential scanning are generally used to form metal tubes. The two most important disadvantages of circumferential scanning are its lower bending angle and the time interval required between each scan for cooling purpose. In this research, a novel cooling strategy during laser tube bending with circumfe...
متن کاملCrack in a 2D beam lattice: Analytical solutions for two bending modes
We consider an infinite square-cell lattice of elastic beams with a semi-infinite crack. Symmetric and antisymmetric bending modes of fracture under remote loads are examined. The related long-wave asymptotes corresponding to a continuous anisotropic bending plate are also considered. In the latter model, the symmetric mode is characterized by the square-root type singularity, whereas the antis...
