Latest Electromagnetic radiation Stories

The National Institute of Standards and Technology (NIST) has demonstrated a novel chip-scale instrument made of carbon nanotubes that may simplify absolute measurements of laser power, especially the light signals transmitted by optical fibers in telecommunications networks. The prototype device, a miniature version of an instrument called a cryogenic radiometer, is a silicon chip topped with circular mats of carbon nanotubes standing on end. The mini-radiometer builds on NIST's previous...

Emmy Noether Research Group Leader Wolfram Pernice Achieves Breakthrough at KIT in Building an Efficient Single-photon Detector Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Physicist Dr. Wolfram Pernice of the Karlsruhe Institute of Technology (KIT), in cooperation with colleagues at Yale University, Boston University, and Moscow...

redOrbit Staff & Wire Reports - Your Universe Online A small scale version of the “tractor beam” used by the starship Enterprise to tow other vessels on the television show Star Trek has been crafted by engineers from Scotland and the Czech Republic. The device, which is detailed in the latest edition of the journal Nature Photonics, was built by scientists at the University of St. Andrews and the Institute of Scientific Instruments (ISI) and allows a beam of light to attract...

Optical Materials Express paper details new laser technique with applications in sensing, photovoltaics, optical switches Silica microwires are the tiny and as-yet underutilized cousins of optical fibers. If precisely manufactured, however, these hair-like slivers of silica could enable applications and technology not currently possible with comparatively bulky optical fiber. By carefully controlling the shape of water droplets with an ultraviolet laser, a team of researchers from...

These are the factors that make the NSG Precision spectrophotometer cell very popular all over the planet. From constructing, manufacturing, cutting and polishing, fusing,...

Bodkin Design & Engineering, LLC has been awarded a contract from the U.S. Air Force to develop a high spatial resolution hyperspectral sensor operating in the longwave infrared (LWIR) spectral band. A prototype system will be demonstrated as part of the Air Force Research Laboratory’s ongoing efforts to improve target acquisition and threat assessment to protect both civilian and military assets. Newton, Massachusetts (PRWEB) January 22, 2013 Bodkin Design & Engineering, LLC...

Technische Universität München Researchers from Technische Universität München (TUM) have developed a new generation of image sensors that are more sensitive to light than the conventional silicon versions, with the added bonus of being simple and cheap to produce. They consist of electrically conductive plastics, which are sprayed on to the sensor surface in an ultra-thin layer. The chemical composition of the polymer spray coating can be altered so that even the invisible range of...
