However, products in these sectors such as innovative display solutions and light emitting panels require the integration of different functionalities and demand new mass manufacturing methods and technologies.

The standard mechanism for improving efficiency with a third polymer is by increasing the absorption of light in the device.

Then by shining a light on these modified neurons via a tiny fiber optic cable inserted into the brain researchers can control the activity of the cells as well as their associated behaviors.

That is when high-intensity light was used the mice became aggressive in the presence of an intruder mouse.

When lower-intensity light was used the mice no longer attacked although they were engaged still socially with the intruder#either initiating mating behavior

and for minutes even after the light was turned off. The researchers could also use the light-activated neurons to stop the mice from engaging in particular behaviors.

For example if a lone mouse began spontaneously self-grooming the researchers could halt this behavior through the optogenetic activation of the social neurons.

Once the light was turned off and the activation stopped the mouse would return to its self-grooming behavior.

which light is amplified. When a laser passes through the powder its wavelength is absorbed not fully.

Instead some of the light from the laser scatters and the path length increases because of this multiple scattering#something scientists refer to as the aman effect. his scattered light is emitted then from the powder in a strong diffuse form that is visually similar to a bright LED light.

Yakovlev and colleagues have been able to increase the scattering efficiency by nine orders of magnitude meaning more light can be detected from greater distances.

For example if you look at a galaxy you expect any explosions to roughly be in line with the underlying light you see from that galaxy

and in how small a space the light can be trapped. By coupling electromagnetic waves with surface plasmons the oscillating electrons found at the surface of metals researchers were able to squeeze light into nanosized spaces

but sustaining the confined energy was challenging because light tends to dissipate at a metal s surface.

we have lots of great light absorbers and systems that can create charge separation, but it hard to maintain that separation long enough to extract it to do useful work.

But the light has to get there. A new one-step process to etch nanoscale spikes into silicon lets the maximum amount of sunlight reach a solar cell,

but the anti-reflection is limited to a specific range of light, incident angle, and wavelength, says Andrew Barron, professor of chemistry and of materials science and nanoengineering at Rice university.

In other words it may be possible to control how light is reflected from a metal. The paper appears online in Nature Physics.

Guo and colleagues invented a special transducer that makes the light-to-sound conversion possible.

In this case it turns terahertz light into ultrasound waves and then transmits them. The transducer is made of a mixture of a spongy plastic called polydimethylsiloxane,

Tiny variations in temperature of the light have been mapped painstakingly across the sky by multiple experiments

Light is polarized when its electromagnetic waves are oriented preferentially in a particular direction. Light from the cosmic microwave background is polarized mainly due to the scattering of photons off of electrons in the early universe through the same process by

because the wavelength of light is too large to fit in tiny components needed for integrated circuits. Nanostructured metamaterials however are making it possible to reduce the wavelength of light allowing the creation of new types of nanophotonic devices says Vladimir M. Shalaev scientific director of nanophotonics at Purdue s Birck Nanotechnology Center

Most light absorbing materials have a symmetrical crystal structure meaning their atoms are arranged in repeating patterns up down left right front and back.

The group engineered the miniature silicon system that produces a type of light that is quieter at certain frequencies#meaning it has fewer quantum fluctuations#than

This#squeezed light#is useful for making precise measurements at lower power levels than are required

when using normal light. Although other research groups previously have produced squeezed light the new system generates the ultraquiet light in a way that can be adapted more easily to a variety of sensor applications.#

#This system should enable a new set of precision microsensors capable of beating standard limits set by quantum mechanics#says Oskar Painter a professor of applied physics at Caltech

#Perfect for electronicsin the past squeezed light has been made using so-called nonlinear materials which have unusual optical properties.

This latest work marks the first time that squeezed light has been produced using silicon a standard material.#

When photons-particles of light-strike the beams they cause the beams to vibrate. And the particulate nature of the light introduces quantum fluctuations that affect those vibrations.

Typically such fluctuations mean that in order to get a good reading of a signal you would have to increase the power of the light to overcome the noise.

But by increasing the power you also introduce other problems such as introducing excess heat into the system.

so that the light and beams interact strongly with each other#so strongly in fact that the beams impart the quantum fluctuations they experience back on the light.

And as is the case with the noise-canceling technology used for example in some headphones the fluctuations that shake the beams interfere with the fluctuations of the light.

They effectively cancel each other out eliminating the noise in the light.##This is a demonstration of

#You need the particle nature of light to explain these quantum fluctuations and you need the wave nature of light to understand this interference.#

The light from a low-power infrared laser interacts with the atoms and is transmitted through the fiber-optic cable to register the magnetic field strength.

and the researchers are confident that it will only be a matter of time before they can fill the gap-they say they will do so mainly by boosting the amount of light detected.

Conventional image sensors work by first converting light into electrical signals then combining that information with the red green

When activated by light, these nanoscale motors twist the polymer chains in the gel, which as a result contracts by several centimeters.

as soon as the motors are activated by light they twist the polymer chains in the gel, which makes it contract.
