Divorce in a one-dimensional world

In everyday objects, there is no left without right or front without back. Just as inseparable seem to be the electron's electric charge and its "spin." But in a strictly one-dimensional quantum world, both quantum properties ...

Laser physics: At the pulse of a light wave

Physicists in the Laboratory for Attosecond Physics at Ludwig-Maximilians-Universitaet (LMU) in Munich and at the Max Planck Institute for Quantum Optics (MPQ) have developed a novel type of detector that enables the oscillation ...

Cutting through fog with laser focus

Research from The University of Queensland aimed at controlling light in scattering materials, such as fog or biological tissues, will benefit future biomedical imaging and telecommunications.

Flexible photonic crystal from liquid thin-film metasurface

Photonic crystals are predicted to be one of the wonders of the 21st century. In the 20th century, new understanding of the electronic band structure-the physics that determines when a solid conducts or insulates-revolutionized ...

Space-time metasurface makes light reflect only in one direction

Light propagation is usually reciprocal, meaning that the trajectory of light travelling in one direction is identical to that of light travelling in the opposite direction. Breaking reciprocity can make light propagate only ...

Conductive polymer nanoantennas for dynamic organic plasmonics

Researchers in the Organic Photonics and Nano-optics goup at the Laboratory of Organic Electronics have developed optical nanoantennas made from a conducting polymer. The antennas can be switched on and off, and will make ...
