Hollow 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 کاملHoley 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 کاملAnomalous bending effect in photonic crystal fibers.
An unexpected transmission loss up to 50% occurs to intense femtosecond pulses propagating along an endlessly single-mode photonic crystal fiber over a length of 1 m. A specific leaky-fiber mode gains amplification along the fiber at the expense of the fundamental fiber mode through stimulated four-wave mixing and Raman scattering, leading to this transmission loss. Bending near the fiber entra...
متن کاملBending performance of large mode area multi-trench fibers.
Bending performance of the Multi-trench Fibers (MTFs) has been investigated using the Finite Element Method. Numerical investigations show that MTFs can provide low-loss effective single mode operation under bent configuration, thanks to the resonant coupling of the Higher order Modes (HOMs). Large ratio between the HOMs and the Fundamental Mode (FM) losses can be ensured, although the ratio dr...
متن کاملDesign and characterization of single-mode holey fibers with low bending losses.
As the fiber-to-the-home network construction increased, optical fiber cables are demanded to be easier to handle and require less space. Under this situation, a single mode fiber (SMF) permitting small bending radius is strongly requested. In this paper, we propose and demonstrate a novel type of bending-insensitive single-mode holey fiber that has a doped core and two layers of holes with dif...
