Even the least scientifically-minded people have at least some idea of amplification, thanks to the amps most of us have tucked away in the lounge. That said, turning a small sound into a larger one ...

Liquid droplets and very fine particles can trap light – similar to how light can be caught between two mirrors. As a result, the intensity of the light inside them is amplified. This also happens in ...

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science (Los Angeles, CA) have developed silicon devices using an optical technology that combines light amplification with a ...

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern ...

In a breakthrough development, scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum ...

Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications. Researchers from AMOLF, TU Delft, and Cornell University in the U.S. have ...

Scientists at EPFL, Lausanne, Switzerland, have developed photonic integrated circuits that demonstrated a new principle of light amplification on a silicon chip. They say can be employed for optical ...

The Fiber Optics Group in the School of Engineering at Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland, has developed a technology that will amplify light inside the latest hollow-core ...

Ever since lasers—a word and an instrument stemming from Light Amplification by Stimulated Emission of Radiation—were first perfected, their fierce, pure gleam has been one of the most revolutionary ...

Focusing a femtosecond laser pulse on or inside transparent materials such as glasses or tissue leads to a well-defined deposition of energy by promoting a large density of carriers to the conduction ...

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. Researchers have now been able to ...
