  1. Scientists Develop Low-Loss, All-Fiber System For Strong And Efficient Coupling Between Distant Atoms

    A team of scientists from Waseda University, the Japan Science and Technology Agency, and the University of Auckland developed an integrated, all-fiber coupled-cavities quantum electrodynamics (QED) system, in which a meter-long portion of conventional optical fiber seamlessly and coherently connects two nanofiber cavity-QED systems.

  2. Spin Laser For Ultra-Fast Data Transfer

    A new concept for ultrafast data transfer over fiber optic cables has been developed by engineers at the Ruhr University Bochum. In conventional systems, a laser sends light signals through the cables and the information is encoded in the modulation of light intensity.

  3. Data Transfer By Controlled Noise

    In information technology, multiplexing schemes are used to transmit more signals than the number of available transmission channels.

  4. Energy Monitor Can Find Electrical Failures Before They Happen

    A new system devised by researchers at MIT can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a Coast Guard cutter, the system pinpointed a motor with burnt-out wiring that could have led to a serious onboard fire.

  5. The Random Anti-Laser

    The laser is the perfect light source: when being provided with energy, it generates light of a specific, well-defined colour. It is also possible, however, to create the exact opposite – an object that perfectly absorbs light of a particular colour and dissipates the energy almost completely.

  6. Quantum Optical Cooling Of Nanoparticles

    When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature.

  7. Downsizing The Particle Accelerator

    Munich physicists have succeeded in demonstrating plasma wakefield acceleration of subatomic particles in a miniaturized, laser-driven model. The new system provides a broader basis for the development of the next generation of particle accelerators.

  8. UCI Scientists Are First To Observe And Image All-Important Molecular Vibrations

    By focusing light down to the size of an atom, scientists at the University of California, Irvine have produced the first images of a molecule’s normal modes of vibration – the internal motions that drive the chemistry of all things, including the function of living cells.

  9. Earth's Magnetic Field Measured Using Artificial Stars At 90 Kilometers Altitude

    The mesosphere, at heights between 85 and 100 kilometers above the Earth's surface, contains a layer of atomic sodium. Astronomers use laser beams to create artificial stars, or laser guide stars (LGS), in this layer for improving the quality of astronomical observations.

  10. Coherent Introduces High-Power 405 nm Compass Laser
    Coherent, Inc.has expanded its CompassTM family of OEM solid-state lasers by introducing the Compass 405-50, which delivers over 50 milliwatts of CW (continuous-wave) output at a wavelength of 405 nm.
