... speaking, single photon detection has not been something pursued very heavily at the wavelengths used for telecommunication signals. Part of the problem is that performance of single photon detectors ...
In a new study, physicists have invented a simple structure called a meta-screen, designed to focus light into tiny spots smaller than the wavelength of the photons in use.
... , Germany, and lead author of the paper describing the observations. "When we combined data at various wavelengths, we were able to tease apart what's going on in different parts of this intriguing ...
... metres, studies the formation of new stars and planets using light with a short wavelength (submillimetre). The Physical Sciences division of the Netherlands Organisation for Scientific Research (NWO ...
... including UK scientists, have been able to compare what the planet looks like at different wavelengths, allowing them to study the physical conditions and dynamics of the planet's atmosphere. These ...
... ) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength Demonstrator Array (LWDA). The measurements were obtained during field tests and calibration of two ...
... rays emitted in these scenarios have the equivalent energy to that of all the stars in an entire galaxy over all wavelengths.
Until now, however, existing ground-based gamma-ray detectors have not ...
... generally been assumed that animals are unable to sense the presumably deleterious UVB wavelengths.”
Many arthropods and vertebrates were known to have body parts that reflect in UV and photopigments ...
... ) laser, which is even less likely to damage delicate vocal-cord tissue. The use of specific wavelengths of laser light to target blood vessels was originally applied to the removal of vascular skin ...
... -defined comb teeth. On the other hand, the filtering approach can cover a broader range of wavelengths. Four or five filtering cavities in parallel would provide a high-precision comb of about 25,000 ...
... it is particularly difficult to pass light through a hole smaller than half the wavelength of the light used. With the help of fellow scientists, researchers at Delft University of Technology have ...
... called near-field scanning optical microscopy fibers, which can resolve features smaller than the wavelength of the light.
The researchers tested the device by measuring ultrashort pulses focused by ...
