At this point, optical fiber is able to focus beams of light into extremely narrow space. AS light travels through the wire, the latter gets narrower and narrower, until it finally reaches a thickness of only a few hundred nanometers. From that moment on – depending on the wavelength of the light itself –... |

Scientists at the US Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have recently developed a new type of nanostructures that is extremely efficient in capturing, filtering and steering light at the nanoscale. The group, based at the Berkeley Lab Molecular Foundry, says that th... |

Scientists at the Georgia Institute of Technology (Georgia Tech) announce the completion of a new type of solar cells, one that may not need to be located on traditional surfaces, such as rooftops. The innovation makes use of nanostructures grown directly on optical fibers, and coated with light-sensitive dyes. This ... |

Most of the computers connected to the Internet today still use standard copper cables for transmitting information, which is carried aboard electrons. The core of the World Wide Web is, however, made up of fiber optic cables, which rely on data being sent via photons. The latter particles are far more “qualifi... |

Technion-Israel Institute of Technology researchers have recently announced that they have devised a way of using telecommunications-grade fiber optic cables to detect war-time underground tunnels, like those used by Hamas in the Gaza strip to smuggle in weapons across the Israeli border. Their finds are to be presen... |

Basically, any liquid column should be able to act as a guide for light, thus behaving similarly to optical fibers. The problem with these liquid fiber optics is that they become unstable after reaching a physical limitation known as the Rayleigh-Plateau instability which states that in free-fall conditions the lengt... |

Although the Universal Serial Bus (USB) interface is currently the most popular connectivity option in most desktop and portable computing systems, but, nevertheless, it does have its shortcomings, the most important such issue being related to the the distance limitation of the USB cables. And in order to solve this... |

One of the good things about the 21st century is that we have Internet access, I mean, not all the people in the world have Internet access, that's why AMD has the 50x15 program up and running but there still a fair amount of people that do have Internet access and it has become a part of our, let' say cult... |
