Leap in lidar could improve safety, security of new technology

Whether it's on top of a self-driving car or embedded inside the latest gadget, Light Detection and Ranging (lidar) systems will likely play an important role in our technological future, enabling vehicles to 'see' in real-time, ...

High-order synthetic dimensions in waveguide photonic lattices

In physics, a very intuitive way of describing the evolution of a system proceeds via the specification of functions of the spatiotemporal coordinates. Yet, there often exist other degrees of freedom in terms of which the ...

Toward lasers powerful enough to investigate a new kind of physics

In a paper that made the cover of the journal Applied Physics Letters, an international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression ...

New method measures temperature within 3-D objects

University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in ...

Looping X-rays to produce higher quality laser pulses

Ever since 1960, when Theodore Maiman built the world's first infrared laser, physicists dreamed of producing X-ray laser pulses that are capable of probing the ultrashort and ultrafast scales of atoms and molecules.

Researchers observe branched flow of light for the first time

A team of researchers from the Technion – Israel Institute of Technology has observed branched flow of light for the very first time. The findings are published in Nature and are featured on the cover of the July 2, 2020 ...

Laser takes pictures of electrons in crystals

Microscopes of visible light allow scientists to see tiny objects such living cells. Yet, they cannot discern how electrons are distributed among atoms in solids. Now, researchers with Prof. Eleftherios Goulielmakis of the ...

Light from inside the tunnel

Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material processing. Physicists ...

Researchers employ antennas for angstrom displacement sensing

The Micro-nano Optics and Technology Research Group led by Prof. Lu Yonghua and Prof. Wang Pei from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) realized nanometric displacement ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

ChipScope – a new approach to optical microscopy

For half a millennium, people have tried to enhance human vision by technical means. While the human eye is capable of recognizing features over a wide range of size, it reaches its limits when peering at objects over giant ...

Quantum entanglement demonstrated aboard orbiting CubeSat

In a critical step toward creating a global quantum communications network, researchers have generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kilograms and orbiting the Earth.

Plug-and-play lens simplifies adaptive optics for microscopy

Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep into biological samples, ...
