(Nanowerk News) Researchers described a new strategy of designing metamolecules that incorporates two independently controllable subwavelength meta-atoms. This two-parametric control of the ...

The reliable manipulation of the speed at which light travels through objects could have valuable implications for the development of various advanced technologies, including high-speed communication ...

Engineers built a nanoscale optical device that uses voltage to control light's phase and intensity, advancing quantum communication and compact optical technologies. The device, developed by ...

Quantum effects are generally thought of as small and fragile. Typically, we’re only able to detect them when things are tiny and kept near absolute zero, and they’re swamped by non-quantum effects ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

When we observe laser light, we typically measure its intensity, and so wave amplitude. The phase, which encodes further details of the laser's internal workings, was obscure — but fresh light is ...

We have used time-resolved fluorescence resonance energy transfer (TR-FRET) to determine the role of myosin essential light chains (ELCs) in structural transitions within the actomyosin complex.

This two-parametric control of the metamolecule secures the complete control of both amplitude and the phase of light. A KAIST research team in collaboration with the University of Wisconsin-Madison ...
