Technique to see objects hidden around corners

A driverless car is making its way through a winding neighborhood street, about to make a sharp turn onto a road where a child's ball has just rolled. Although no person in the car can see that ball, the car stops to avoid ...

Sunlight funnel collects light from all directions

Researchers have designed a light-harvesting funnel that absorbs sunlight from any direction and concentrates it onto smaller areas, such as high-performance solar cells. By stacking multiple funnels, each tuned to a different ...

A marriage of light-manipulation technologies

Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving ...

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons ...

Super-resolution microscopy in both space and time

Super-resolution microscopy is a technique that can "see" beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest ...

Optical distance measurement at record-high speed

Microresonator-based optical frequency combs enable highly-precise optical distance ranging at a rate of 100 million measurements per second – publication in Science: Scientists of Karlsruhe Institute of Technology (KIT) ...

A laser focus on super water-repellent metals

In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.

Researchers turn light upside down

Researchers from CIC nanoGUNE (San Sebastian, Spain) and collaborators have reported in Science the development of a so-called hyperbolic metasurface on which light propagates with completely reshaped wafefronts. This scientific ...

Seeing nanoscale details in mammalian cells

In 2014, W. E. Moerner, the Harry S. Mosher Professor of Chemistry at Stanford University, won the Nobel Prize in chemistry for co-developing a way of imaging shapes inside cells at very high resolution, called super-resolution ...
