  1. Non-Destructive, Sub-Angstrom Level Measurement Of A Nanofiber

    Researchers at the University of Maryland's Joint Quantum Institute (JQI) and the Army Research Laboratory (ARL) have devised a unique method to measure the radius of a nanofiber with sub-angstrom-scale sensitivity — without destroying the nanofiber with chemicals and heat in the process, as current scanning electron microscopy (SEM) techniques tend to do.

  2. Researchers Build Tiny Yet Ultra-Precise Environmental Sensor

    Researchers at the Hebrew University of Jerusalem's Center for Nanoscience and Nanotechnology have successfully fabricated an on-chip sensor so sensitive that it can measure unprecedentedly minute variations in temperature and other environmental parameters.

  3. 'Squeezed' Light Cools Object Below Quantum Limit

    Physicists at the National Institute of Standards and Technology (NIST) has successfully cooled a microscopic aluminum drum to an unprecedented one-fifth of a single quantum of energy, the coldest a mechanical object has ever approached absolute zero.

  4. MIT's Low-Cost Microscope Images Micron-Sized Particles

    Researchers at the Massachusetts Institute of Technology (MIT) have built a portable yet powerful microscope capable of chemically identifying individual micron-sized particles.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.
