Science invention
Optical memory - from nanolaser to 1 Tbit / inch2
Researchers in the United States have just succeeded in creating a nanolaser device that converges a beam of light with a power of 200 nW into a small spot less than 35…
Science invention
Airy optical beam was first observed
For the first time, scientists have observed unusual optical beams called Airy rays. Unlike other light rays, Airy rays have the ability to maintain diffraction in a far…
Science invention
Made of gold aluminum, black platinum and green silver with a laser machine
By using a tabletop laser, the University of Rochester optical scientists have turned pure aluminum into yellow, green, gray and other colors. All metals are t
Science invention
Black hole created from light
Professor Ulf Leonhardt and Dr. Friedrich König used high-intensity light pulses to create an artificial 'event horizon' - a feature that identifies a black hole and is…
Science invention
Atoms store 2D images in record time
Physicists in Israel have shown that 2D images of light can be projected into atomic gas, stored there and recovered in time to 9 9s later. Although this is not the time
Science invention
Seesaw mechanism explains light dark energy particles
Dark energy - a mysterious form of matter that is thought to be responsible for the rapid expansion of the universe - could be the result of eight interactive fields thr…
Science invention
Nano antenna converges laser light
What do you get when you combine the quantum laser cascade with an optical antenna? The answer, according to US researchers, is a device that creates a tiny spot of ligh…
Science invention
Invisible tunnel design: Create an electromagnetic
It could be called Harry Porter's invisibility sleeve. New calculations have found a way to create an electromagnetic
Science invention
Cooling with Polariton
Shining light on an object to reduce its temperature seems a rather strange way, but laser cooling is frequently used in physics, especially to create super-cold samples…
Science invention
Negative refractive index in iron materials from natural metal in high frequency range
Physicists in Germany claim they have for the first time discovered a material with a natural negative refractive index, instead of the usual positive refractive index.…
Science invention
Controlling light by matrix of nanoparticles
Light can be led and manipulated on the nanometer scale using the effects of plasmonics physics, according to the latest calculations published by a team of researchers…
Science invention
Magnets can change the color of liquids
The University of California, Riverside nanologists have succeeded in controlling the color of tiny iron oxide particles suspended in water simply by applying an externa…
Science invention
Turn rubium atoms into a single photon server
Each time you turn on a light bulb, there is the energy of 10 to 15 visible photons, the fundamental particles of light, that will illuminate the room every second. If t…
