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 ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Scientists in Japan have managed to manipulate light as though it was being influenced by gravity. By carefully distorting a photonic crystal, the team was able to invoke “pseudogravity” to bend a ...

A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

When propagating through a material, a laser beam of significant intensity slightly modifies the density of the physical medium and generates tiny vibrations. These acoustic oscillations distort the ...

Slightly noisy signals can turn into rare large spikes in an optical fiber’s output, in much the same way as unpredictable weather conditions occasionally create monstrous, isolated oceanic waves, ...
