Fiber laser fiber

(CLEO). Conference on Lasers and Electro-Optics, 2005., 2005
Fiber lasers performance continues to increase due to advances in fiber design, with developments such as large mode area fibers, all-glass pump combiners, microstructured fiber and air-clad fiber allowing higher peak and average power.

Capturing hair assemblies fiber by fiber

ACM SIGGRAPH Asia 2009 papers, 2009
Hair models for computer graphics consist of many curves representing individual hair fibers. In current practice these curves are generated by ad hoc random processes, and in close-up views their arrangement appears plainly different from real hair.

Fiber–fiber interaction in concentrated suspensions: Disperse fibers

Journal of Rheology, 1999
A hypothesis for fiber–fiber interaction in planar randomly oriented concentrated fiber suspensions is proposed and tested. The idea is that at sufficiently high fiber concentrations, friction and lubrication at fiber–fiber contact points are the dominant interaction mechanisms.

Endlessly single-mode photonic crystal fiber.

Optics Letters, 1997
We made an all-silica optical fiber by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes. An effective-index model confirms that such a fiber can be single mode for any wavelength.

Numbers of Fiber-to-Fiber Contacts in General Fiber Assemblies

Textile Research Journal, 1977
General formulas are derived for the estimation of the number of fiber-to-fiber contacts in fiber assemblies with arbitrary distributions of orientation and fiber length. The average number of contacts per unit volume of an assembly ñv is given by [Formula: see text] where [Formula: see text] In this equation fi is the density function of ...

Fiber–fiber interaction in concentrated suspensions: Dispersed fiber bundles

Journal of Rheology, 1999
A model is proposed to describe the rheology of planar randomly oriented concentrated fiber bundle suspensions in a shear-thinning matrix. The approach is that, at high fiber volume fractions, the dominant interaction mechanisms are friction and lubrication at the fiber–fiber contact points.

Fiber Bragg grating technology fundamentals and overview

, 1997
The historical beginnings of photosensitivity and fiber Bragg grating (FBG) technology are recounted. The basic techniques for fiber grating fabrication, their characteristics, and the fundamental properties of fiber gratings are described.

All-silica single-mode optical fiber with photonic crystal cladding.

Optics Letters, 1996
We report the fabrication of a new type of optical waveguide: the photonic crystal fiber. It consists of a pure silica core surrounded by a silica-air photonic crystal material with a hexagonal symmetry. The fiber supports a single robust low-loss guided

Fibers and More Fibers

Science News, 1966
> MODERN ALCHEMY is changing not base metals, but polymers into gold. The manufacture of polymer fibers is one of today's fastest-expanding industries. With increasing demands for fibers for clothing, tires, space applications and a variety of other needs, the consumption of both natural and man-made fibers has increased by leaps and bounds during the ...

Application Challenges in Fiber and Textile Electronics

Advances in Materials, 2019
Modern electronic devices are moving toward miniaturization and integration with an emerging focus on wearable electronics. Due to their close contact with the human body, wearable electronics have new requirements including low weight, small size, and ...
