  1. Finnish Researchers Use Plasmonic Nanolaser In Dark And Bright Modes

    Researchers at Aalto University in Finland have demonstrated for the first time a new lasing technique operating at visible light frequencies, in both bright and dark modes, by utilizing metallic nanoparticles arranged in a periodic array. Their findings make possible the creation of small and ultrafast on-chip light sources.

  2. U.S. Military's Laser Weapons Development Get Funding Boost

    United States President Barack Obama's signing of the year-end defense bill will increase by more than half the U.S. military's funding for laser weapon systems for fiscal year 2017.

  3. Making Flat Optical Lenses By Stacking Metasurfaces

    Engineers at California Institute of Technology (Caltech) have successfully demonstrated how to stack metasurfaces to form flat optical lenses that can be mass-produced and integrated with electronics and image sensors.

  4. Building A Single-Atom Quantum Optical Circulator

    Scientists at the Technische Universität Wien (TU Wien) in Vienna, Austria have devised a new method to control the flow of light along perpendicular and intersecting glass fibers using a single atom. Building such a nanoscale optical element for controlling light, including single photons, can be important for optical signal processing of quantum information.

  5. Scientists Improve Modulation Bandwidth, Laser Operation Of Transistor Laser Device

    Engineers Nick Holonyak Jr. and Milton Feng at the University of Illinois continue to enhance the remarkable properties of the transistor laser they invented in 2004. Two of their recent studies explain how they improved the fundamental modulation bandwidth of the transistor and the laser operation of the device to make possible energy-efficient, high-speed data transfer in optical and 5G wireless communications.

  6. Upgraded LIGO Resumes Hunt For Colliding Black Holes And Gravitational Waves

    The Laser Interferometer Gravitational-Wave Observatory (LIGO) is ready to resume tracking colliding black holes and the elusive gravitational waves these cataclysmic events generate through space-time.

  7. Scientists Create First "Water-Wave" Laser

    For the first time, scientists have generated lasers from the interaction of light and water waves. This "water-wave" laser can find future application in optofluidic devices and "lab-on-a-chip” devices for studying cell biology and delivering drugs at the nanoscale.

  8. MIT Builds Miniature Terahertz-Driven, All-Optical Electron Gun

    Researchers at the Massachusetts Institute of Technology (MIT), in collaboration with German scientists, have built a matchbox-sized electron gun that uses laser-generated terahertz radiation (instead of radio frequency fields) to accelerate electrons, while consuming far less power than state-of-the-art electron guns.

  9. STReM Technique Captures High-Speed, Super-Resolution Images Without Need For A Fast Camera

    Rice University researchers have refined a Nobel Prize-winning microscopy technique to capture fluorescing molecules at a frame rate 20 times faster than other laboratory cameras.

  10. Foil-Based Ultraviolet LEDs Purify Water, Kill Pathogens

    Researchers at Ohio State University have successfully demonstrated a technique to grow nanowire light-emitting diodes (LEDs) on thin metal foils. These unique deep-ultraviolet (DUV) LEDs are viable alternatives to conventional UV lamps for water, food, and medical equipment sterilization.
