When cold atoms meet nano: A wired quantum node

Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. Using fiber-addressable atoms, they have created the first wired atomic entangled state that ...

Physicists create exotic electron liquid

By bombarding an ultrathin semiconductor sandwich with powerful laser pulses, physicists at the University of California, Riverside, have created the first "electron liquid" at room temperature.

New progress toward chip-based ghost imaging

For the first time, researchers have shown that the non-conventional imaging method known as ghost imaging can be performed using a low-cost, chip-based light-illuminating device. This important step toward chip-based ghost ...

Ceramic holds promise for greener optical devices

A lead-free ceramic that could be used in applications ranging from optical sensors and switches to creams for protecting against ultraviolet (UV) light has been developed by A*STAR researchers.

'Quiet' light

Spectrally pure lasers lie at the heart of precision high-end scientific and commercial applications, thanks to their ability to produce near-perfect single-color light. A laser's capacity to do so is measured in terms of ...

Virtual lens improves X-ray microscopy

With X-ray microscopes, researchers at PSI look inside computer chips, catalysts, small pieces of bone, or brain tissue. The short wavelength of the X-rays makes details visible that are a million times smaller than a grain ...

Research team demonstrates fractal light from lasers

Fractal patterns are common in nature, including in the geometric patterns of a tortoise shell, the structure of a snail shell, the leaves of a succulent plant that repeat to create an intricate pattern, and the frost pattern ...

Environmentally stable laser emits exceptionally pure light

Researchers have developed a compact laser that emits light with extreme spectral purity that doesn't change in response to environmental conditions. The new potentially portable laser could benefit a host of scientific applications, ...

Fiber sensors may leave the jacket on

Optical fibers enable the internet, and they are practically everywhere: underground and beneath the oceans. Fibers can do more than just carry information: they are also fantastic sensors. Hair-thin optical fibers support ...

Nonlinear integrated quantum electro-optic circuits

Physicists envision that the future of quantum computation networks will contain scalable, monolithic circuits, which include advanced functionalities on a single physical substrate. While substantial progress has already ...

A new home for optical solitons

Laser physicists based at the Laboratory for Attosecond Physics run by the Max Planck Institute of Quantum Optics and the Ludwig-Maximilian University have, for the first time, generated dissipative solitons in passive, free-space ...
