  1. Thermally-Painted Metasurfaces Yield Perfect Light Absorbers For High-Tech Applications

    Researchers have discovered that the ancient technique of heating metal to create vibrant colors creates a nanostructured surface that acts as a perfect light absorber. Perfect light absorbers — materials that absorb more than 99% of a certain color — can be used for sensing, solar panels, anti-counterfeiting and stealth technologies

  2. More Sustainable Conversion Of Amino Acids: With Light Instead Of With Heat

    PhD-candidate Cecilia Bottecchia was one of the first to succeed in converting amino acids, which can be used for medication, with the help of visible light. This is more sustainable than conventional methods, in which the conversion is powered by heating.

  3. The Holy Grail Of Nanowire Production

    EPFL researchers have found a way to control and standardize the production of nanowires on silicon surfaces. This discovery could make it possible to grow nanowires on electronic platforms, with potential applications including the integration of nanolasers into electronic chips and improved energy conversion in solar panels.

  4. NIST Physicists ‘Flash-Freeze’ Crystal Of 150 Ions

    Physicists at the National Institute of Standards and Technology (NIST) have “flash-frozen” a flat crystal of 150 beryllium ions (electrically charged atoms), opening new possibilities for simulating magnetism at the quantum scale and sensing signals from mysterious dark matter.

  5. New Laser Methods Create Dazzling Colors On Metals

    A variety of laser-based techniques can be used to produce colorful artwork on metals. However, each approach typically requires a different type of laser and very specific settings.

  6. Iridian Spectral Expands With New Coating Systems And Processing Equipment

    Iridian has recently added new coating systems and processing equipment to significantly expand our capacity and capability to continue to provide technically and commercially leading optical filters to our customers.

  7. A Polariton Filter Turns Ordinary Laser Light Into Quantum Light

    An international team of researchers led out of Macquarie University has demonstrated a new approach for converting ordinary laser light into genuine quantum light.

  8. Optoscribe And Sumitomo Electric Announce Strategic Cooperation To Deliver Multicore Fiber Components

    Optoscribe, a world-leading supplier of 3D glass-based integrated photonics components, and Sumitomo Electric Industries, a world-class optical fiber cable and component manufacturing technology supplier, are delighted to announce the formation of a strategic cooperation to provide multicore fiber (MCF) components for datacom and telecom applications.

  9. New Imaging Technology Captures Movement Of Quantum Particles With Unprecedented Resolution

    Excitons — electrically neutral quasiparticles — have extraordinary properties. They exist only in semiconducting and insulating materials and can be easily accessed in two-dimensional (2D) materials just a few atoms thick, such as carbon and molybdenite.

  10. Engineered Metasurfaces Reflect Waves In Unusual Directions

    In our day lives, we can find many examples of manipulation of reflected waves such as mirrors to see our reflections or reflective surfaces for sound that improve auditorium acoustics. When a wave impinges on a reflective surface with a certain angle of incidence and the energy is sent back, the angle of reflection is equal to the angle of incidence.
