Study finds single photons cannot exceed the speed of light
Nano-LEDs emit full visible spectrum of light
Computing at the speed of light: Team takes big step toward much faster computers
University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines.
Best of Last Week – A way to measure variations in the speed of light, a slower universe and plucking hair
Camera chip provides superfine 3-D resolution
Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, ...
New insights found in black hole collisions
New research provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger black hole.
The first ever photograph of light as both a particle and wave
(Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at ...
New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Engineers efficiently 'mix' light at the nanoscale
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but ...
Two photons strongly coupled by glass fiber
Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created ...
Getting sharp images from dull detectors: Operating in the fuzzy area between classical and quantum light
Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons—-the particle complement ...
Scientists twist radio beams to send data: Transmissions reach speeds of 32 gigabits per second
Building on previous research that twisted light to send data at unheard-of speeds, scientists at USC have developed a similar technique with radiowaves, reaching high speeds without some of the hassles that ...
Ultra-thin, high-speed detector captures unprecedented range of light waves
New research at the University of Maryland could lead to a generation of light detectors that can see below the surface of bodies, walls, and other objects. Using the special properties of graphene, a two-dimensional ...
