Researchers tunnel to a new light source

With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, wasted energy is a factor as important as the amount of green energy produced. Thus, solid-state lighting based upon light-emitting ...

The stacked color sensor

Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity ...

The path length of light in opaque media

A seemingly paradoxical prediction in physics has now been confirmed in an experiment: No matter whether an object is opaque or transparent, the average length of the light's paths through the object is always the same.

Ions in the spotlight

The results of a research group from the Institute of Physics at the University of Freiburg has been given a special place in Nature Photonics. An accompanying "News & Views" article in the print version of the science journal ...

Illuminated pajamas treat newborns

Alone, naked, and with their eyes covered for protection: this is how newborns lie in incubators when they are being treated for jaundice. Irradiation with blue light in an incubator is necessary because toxic decomposition ...

Quantum dots visualize tiny vibrational resonances

In the late 18th century, Ernst Chladni, a scientist and musician, discovered that the vibrations of a rigid plate could be visualized by covering it with a thin layer of sand and drawing a bow across its edge. With the bow ...

Liquids take a shine to terahertz radiation

In a significant breakthrough, scientists at the Tata Institute of Fundamental Research (TIFR), Mumbai, have devised a high-power radiation source in the terahertz (THz) region of the electromagnetic spectrum. This study, ...

Guiding the random laser

At its most basic level, a random laser is precisely what its name implies; random. It's random in the spectrum of light it produces and in the way that light is emitted, making what could be an extremely versatile laser ...

The world's shortest laser pulse

ETH researchers succeeded in shortening the pulse duration of an X‑ray laser to only 43 attoseconds. With a time resolution in the range of a few quintillionths of a second, they are now able for the first time to observe ...

Imaging probe printed onto tip of optical fiber

Combining speed with incredible precision, a team of Molecular Foundry scientists and industry users developed a way to print extremely small devices on the tip of a glass fiber as thin as a human hair. These tiny devices ...

Making fluorescent chips using an inkjet printer

Every mealtime it's the same thing. Your child clutching their stomach and complaining about tummy ache. You as parents are at your wits' end, and nothing you try from your home medicine cabinet is having any effect. Could ...
