Ultrashort attosecond light pulses, when used as the "shutter" in an imaging or spectroscopy system, can probe into the attosecond realm to see how the actual motions of electrons...
In contrast to the Space Elevator concept, in which high-power continuous-wave lasers beam light to photovoltaic cells attached to a vehicle that rides into space on a cable at...
A new type of contact lens created by researchers at Xceed Imaging (Petach-Tikva, Israel), Tel Aviv University (Tel Hashomer, Israel), and Bar-Ilan University (Ramat-Gan, Israel...
Airlines often use marginal pricing to sell empty seats. But for airline seats the marginal cost does not tend to zero dollars and hence the seats are never free.
LightTools 6.3 illumination design and analysis software adds an alternate optimization engine that supplements the existing optimizer and lets users address a broader range of...
Thanks to the advent of precision glass molding–which enables the cost-effective manufacture of aspheric glass lenses–glass aspheres can now be incorporated in cost-conscious ...
Inkjet printing is so good at positioning and meting out the right quantity of material that it can be used not just for producing documents, but in industry as well–for example...
Indium gallium arsenide (InGaAs) photodiodes and quantum-well IR photodetectors are typical methods of choice for near-IR detection and imaging applications in the spectral region...
A miniaturized sensor developed at the Georgia Institute of Technology, which is claimed to be the first such device able to produce narrowband multispectral imagery in real time...
Single-package hybrid optical integration of two semiconductor laser chips with a high-resolution wavelength discriminator has been used to realize a tunable terahertz source ...
Semiconductors that make up an LED have such a high refractive index that much of the light produced by a conventional LED never escapes from the device into the surrounding air...
A new type of contact lens created by researchers at Xceed Imaging (Petach-Tikva, Israel), Tel Aviv University (Tel Hashomer, Israel), and Bar-Ilan University (Ramat-Gan, Israel...
Nitrides offer considerable advantages over other materials for ultraviolet detection. Recently, they proved useful for creating the world’s first UV single-photon detectors with...
The quest for subwavelength imaging through anisotropic metamaterials has produced a design for a bilayer lens that can restore a nearly perfect image.
Believe it or not, researchers at the University of Wollongong (New South Wales, Australia) have discovered that peeling adhesive tape emits unpolarized terahertz radiation.
