Nano-patterned fibres shine more brightly

Fiber laser systems shine brightly

In fact, the commercial potential of the EDFA is such that the telecommunications industry has invested enormous resources in doped-fiber amplifier development over the past ten years. As a result, steady advances have occurred in fiber fabrication and design as well as in the understanding of the spectroscopic properties of rare-earth ions in a glass matrix. This research has also driven devel...

Spiders spinning electrically charged nano-fibres.

Most spider threads are on the micrometre and sub-micrometre scale. Yet, there are some spiders that spin true nano-scale fibres such as the cribellate orb spider, Uloborus plumipes. Here, we analyse the highly specialized capture silk-spinning system of this spider and compare it with the silk extrusion systems of the more standard spider dragline threads. The cribellar silk extrusion system c...

"It's more than a shoe shine--you're touching lives".

More light in Polish optical fibres

Optical communications infrastructure is undergoing an intense development in his country now. A number of international investors and domestic operators are building from the beginning, modernizing or developing proprietary network or leasing wide area systems on a large scale. The aggregate level of these processes is of the order of bil. $. Despite of this the network is not homogeneous, has...

Nano-Scale Patterned Magnetic Tunnel Junction and Its Device Applications

Nano-scale patterned techniques, DCpulsed-current-driven magnetization switching and spin-dependent transport properties of magnetic tunnel junctions (MTJs) are presented in this paper. The experiments show that the spin transfer torque (STT) plays a main switching role in the magnetization current switching and the current-induced circular magnetic field plays an assisted-switching role in the...
