Strain and Curvature Stability Enhanced SMF Introduction
In this paper, the strain insensitive single mode optical fiber with low nonlinear effects and ultra low bending loss (BL), appropriate for small curvature radius installation, is presented. The suggested design method is based on the reverse engineering

Ultra low bending loss equiangular spiral photonic crystal fibers in the terahertz regime [PDF]
An Equiangular Spiral Photonic Crystal Fiber (ES-PCF) design in Topas® for use in the Terahertz regime is presented. The design shows ultra low bending loss and very low confinement loss compared to conventional Hexagonal PCF (H-PCF).

Hollow antiresonant fibers with low bending loss [PDF]
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.

In this paper, a low-loss 90°-bending design in femtosecond laser-induced double-line waveguides is theoretically proposed and experimentally demonstrated. The bending is realized based on the total internal reflection of a corner mirror (made by precise

Two-dimensional optical ring resonators based on radial Bragg resonance [PDF]
A Bragg-reflection-based ring resonator is proposed and analyzed. Closed-form expressions for the field and dispersion curves for radial Bragg gratings and photonic bandgap crystals are derived.

Birefringence analysis of multilayer leaky cladding optical fibre [PDF]
We analyse a multilayer leaky cladding (MLC) fibre using the finite element method and study the effect of the MLC on the bending loss and birefringence of two types of structures: (i) a circular core large-mode-area structure and (ii) an elliptical ...

Computational studies of light acceptance and propagation in straight and curved multimodal active fibres [PDF]
A Monte Carlo simulation has been performed to track light rays in cylindrical multimode fibres by ray optics. The trapping efficiencies for skew and meridional rays in active fibres and distributions of characteristic quantities for all trapped light ...

Low-loss criterion and effective area considerations for photonic crystal fibers [PDF]
We study the class of endlessly single-mode all-silica photonic crystal fibers with a triangular air-hole cladding. We consider the sensibility to longitudinal nonuniformities and the consequences and limitations for realizing low-loss large-mode area ...

Effective area of photonic crystal fibers [PDF]
We consider the effective area A_eff of photonic crystal fibers (PCFs) with a triangular air-hole lattice in the cladding. It is first of all an important quantity in the context of non-linearities, but it also has connections to leakage loss, macro ...

Bend loss in highly multimode fibres
We investigate the bend loss of highly multimode air-clad microstructured polymer optical fibre which displays low bend loss for small bend radii. After repeated bending the loss approached a plateau, decreasing significantly after a characteristic length. The loss at a particular point depended on the configuration of the fibre preceding that point. A
