which normally emits green light when illuminated with blue light. The emission of Dendra 2 is shifted however into the red
when it is irradiated by intensive violet or ultraviolet (UV) laser light. Two-laser combination Dempsey and Pantazis specifically discovered that
when Dendra 2 is irradiated by both a blue and a red laser at the same time,
the protein's colour can also change to red. For this dual-colour illumination low intensity laser light is sufficient.
In contrast to high intensity violet or ultraviolet (UV) irradiation it does not damage living cells.
ETH professor Pantazis and his colleagues then had an idea of how this finding could be deployed in light microscopy.
when used individually, two different laser beams cannot change a chameleon protein's colour. But when the two beams are combined
the proteins that are activated not at the same time by the two lasers retain their original colour. The researchers have developed a simple and inexpensive colour filter,
which can be used with the conventional confocal laser microscopes that are found in many biomedical research institutes.
When mounted between the laser source and object the filter divides the laser light into separate blue
and red beams that are directed on to a small focal point on the object. Examination of dynamic processes In the case of the zebrafish larva,

#Unique Gold Nano Spirals Could Help Prevent Identity Theft By Will Soutterthe spirals react in a unique way to polarized infrared light,
In this new research, published in the Journal of Nanophotonics on May 21st, the nanospirals the smallest ever reported,
Because these spirals are smaller than the wavelength of visible light, they exhibit unusual optical properties.
For example, when the spirals are lit up with infrared laser light, they produce visible blue light. In fact, several crystals are known to produce this effect,
which is known as harmonic generation or frequency doubling. The synthetic crystal beta barium borate was previously the strongest frequency doubler known;
however, the new nano-spirals are capable of emitting even higher intensity blue light. The nano-spirals also exhibit a distinctive reponse to polarized light-the amount of blue light produced changes considerably as the angle of polarization is turned through 360°.
°This effect is noticeable with linear polarized light, but even more pronouced with circular polarized light.
When the direction of polarization matches the direction of the spiral, the electrons in the material are pushed towards the middle of the spiral,
and a large amount of blue light is produced. In contrast, when the opposite direction of polarization is applied (e g. clockwise polarized light with anticlockwise spirals),
almost no blue light is emitted. This is because the electrons are pushed to the outside of the spiral,
which creates a destructive interference and weakens the optical effect. The gold nano-spirals in this study were created using scanning electron-beam lithography-platinum
or silver would also be suitable materials, as they have similar corrosion-resistant properties. The tiny amount of metal used in the spirals means they are not expensive to make-however,
significant investment in the advanced lithography equipment is required. Because of the strong frequency doubling response to circularly polarized light,
it would be fairly easy to check for the presence of the spirals on a surface with a device similar to a barcode reader.
The optical lattice was produced by two laser beams traveling in opposite directions, the fields of which together form a sinusoidal periodic pattern in a single dimension.
The researchers applied light to either ionize or charge neutral ytterbium atoms rising from a tiny heated oven.
The atoms were cooled then down with more laser light to a temperature immediately above absolute zero. Using voltages applied to metallic surfaces in very close proximity,
the new approach involves bouncing laser light off individual bacteria under the microscope, creating holographic images of them,
"Employing laser holographic techniques, we achieved rapid and label-free identification of bacterial species at the single bacterium level with a single-shot measurement,
in order to measure light scattering patterns of individual bacteria, which can then be used to identify bacteria species for rural areas

It is possible for something to move faster than the phase velocity of light in a medium

For the first time, Harvard researchers have created similar wakes of light-like waves moving on a metallic surface, called surface plasmons,
"Our understanding of optics on the macroscale has led to holograms, Google glass and LEDS, just to name a few technologies.
and harness the power of light on the nanoscale.""The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers
and lenses that could create two-dimensional holograms or focus light at the nanoscale. Surface plasmons are confined to the surface of a metal.
The team discovered that the angle of incidence of the light shining onto the metamaterial provides an additional measure of control
and using polarized light can even reverse the direction of the wake relative to the running wavelike a wake traveling in the opposite direction of a boat."

a laser is focused onto a small spot on the sample by each microlens. The laser light causes the sample to fluoresce,
emitting specific wavelengths of light that differ depending on the molecules that are present. This fluorescence is imaged then back onto the camera.
This is done for thousands of microlenses at once. This multipoint scanning greatly reduces the amount of time necessary to image a sample by simultaneously harnessing thousands of lenses. y recording the color spectrum of the fluorescence
These dyes respond to laser light by fluorescing at specific frequencies so they can be detected and localized with high precision.

When they learned that UV LIGHT was used to disinfect water in certain treatment plants, they began to ask a different question. e thought
if they are already using UV LIGHT, maybe they could use our particles as well, Brandl says. hen we came up with the idea to use our particles to remove toxic chemicals, pollutants,

Today, huge amounts of data are sent incredibly fast through fibre optic-cables cables as light pulses. For that purpose they first have to be converted from electrical signals,
In Bell's days it was a simple, very thin mirror that turned sound waves into modulated light.
In a seminal paper in the scientific journal"Nature Photonics",Juerg Leuthold, professor of photonics and communications at ETH Zurich,
In order to build the smallest possible modulator they first need to focus a light beam whose intensity they want to modulate into a very small volume.
however, dictate that such a volume cannot be smaller than the wavelength of the light itself.
Modern telecommunications use laser light with a wavelength of one and a half micrometers, which accordingly is the lower limit for the size of a modulator.
the light is turned first into so-called surface-plasmon-polaritons. Plasmon-polaritons are a combination of electromagnetic fields
The advantage of this detour is that plasmon-polaritons can be confined in a much smaller space than the light they originated from.
Refractive index changed from the outsidein order to control the power of the light that exits the device,
a laser beam can be split onto two arms by a beam-splitter and recombined with beam combiner.
In the modulator developed by the ETH researchers it is not light beams but rather plasmon-polaritons that are sent through an interferometer that is only half a micrometer wide.
After that, the plasmons are reconverted into light, which is fed into a fibre optic cable for further transmission.
light sources; a pump; and a microfluidics chip with a fluorometer also developed at the University Hospital Zurich.
If UV LIGHT is beamed onto these spiropyran molecules they alter their chemical structure and become charged (polar).
When irradiated with visible light they revert to their original neutral structure. As a result the membrane opens
if irradiated with UV LIGHT and glucose molecules diffuse relatively easily through the membrane from the skin.
If irradiated with visible light considerably fewer glucose molecules pass through the membrane. The measurement involves sticking the measuring head
and irradiating it with visible light; some glucose molecules diffuse through the membrane from the skin.
The process is repeated then with UV LIGHT. The computer then uses these two different readings to calculate the premature baby's blood sugar level.

the photonics advancement aims to improve our ability to detect trace amounts of molecules in diseases,
and measure chemical and biological molecules using a broadband nanostructure that traps wide range of light,
When a powerful laser interacts chemical and biological molecules, the process can excite vibrational modes of these molecules and produce inelastic scattering, also called Raman scattering, of light.
As the beam hits these molecules, it can produce photons that have a different frequency from the laser light.
While rich in details, the signal from scattering is weak and difficult to read without a very powerful laser.
Unfortunately, traditional substrates are designed typically for only a very narrow range of wavelengths. This is problematic because different substrates are needed
if scientists want to use a different laser to test the same molecules. In turn, this requires more chemical molecules and substrates,
because it can trap a wide range of wavelengths and squeeze them into very small gaps to create a strongly enhanced light field.
Instead of needing all these different substrates to measure Raman signals excited by different wavelengths, youl eventually need just one.
