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...
A straightforward way of fabricating nanometer-scale convex lenses developed by researchers at Pohang University of Science and Technology (Pohang, Korea), Sungkyunkwan University...
Believe it or not, researchers at the University of Wollongong (New South Wales, Australia) have discovered that peeling adhesive tape emits unpolarized terahertz radiation.
Researchers at the Clausthal University of Technology (Goslar, Germany), the Laboratorio NEST (Pisa, Italy), and the University of Cambridge (Cambridge, England) have created ...
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 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...
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...
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 ...
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 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...
Even though small second-harmonic-generation (SHG)-based external-cavity green lasers are readily available, the advantages of pure semiconductor laser diodes–such as miniature...
The quest for subwavelength imaging through anisotropic metamaterials has produced a design for a bilayer lens that can restore a nearly perfect image.
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 ...
