Guiding lasers where they need to go is a key part of optics systems, and now engineers at DESY have developed a way to bend laser beams without anything touching them. The light is deflected using an ...

Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times ...

Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its ...

An artistic view of the subwavelength grating made of layered molybdenum diselenide. The red spheres represent molybdenum atoms, and the blue ones represent selenium atoms. Light is trapped within the ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with research groups from the Łódź University of Technology, the Warsaw University of Technology, and the Polish ...
