Transmitting data from space to earth with laser filaments

Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster ...

Scientists prevent critical collapse of higher-order solitons

Solitons are stable objects balanced by diffraction or dispersion and nonlinearity. A fundamental challenge in this field is the stabilization of solitons in multidimensional coordinates, since the 2-D and 3-D solitons in ...

When plasmons reach atomic flatland

Researchers from the MPSD and the Lawrence Berkeley National Laboratory (LBNL) in the United States have discovered a significant new fundamental kind of quantum electronic oscillation, or plasmon, in atomically thin materials. ...

Setting up fundamental bases for information metasurfaces

When illuminated by electromagnetic waves, subwavelength-scale particles of metasurfaces can couple the incident energy to free space with controllable amplitude, phase and polarizations, such that the transmitted wave can ...

Slow light to speed up LiDAR sensors development

Quicker is not always better, especially when it comes to a 3-D sensor in advanced technology. With applications in autonomous vehicles, robots and drones, security systems and more, researchers are striving for a 3-D sensor ...

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 ...
