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 کاملBending-Loss Insensitive Fiber with Hole-Assisted Structure
The characteristics of hole-assisted fiber (HAF) are investigated both numerically and experimentally in terms of its applicability as a bending-loss insensitive fiber (BIF). We show that HAF with the desired mode-field diameter (MFD), bending-loss and cutoff wavelength characteristics can be roughly designed by taking a few specific structural parameters into consideration. We also show that 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 کاملBending Instability of an Accretion Disc Around a Black Hole
We demonstrate that generically an accretion disk around a compact object could have a new type of instability in that the accretion flow need not be symmetric with respect to the equatorial plane even when matter is supplied symmetrically farther out. We find that this behaviour is mainly due to interaction of outgoing matter bounced off the centrifugal barrier and the incoming accretion. We b...
متن کاملProduct Evaluation In Elliptical Helical Pipe Bending
This research proposes a computation approach to address the evaluation of end product machining accuracy in elliptical surfaced helical pipe bending using 6dof parallel manipulator as a pipe bender. The target end product is wearable metal muscle supporters used in build-to-order welfare product manufacturing. This paper proposes a product testing model that mainly corrects the surface directi...
