A theory borrowed from physics to understand how electrons move in semiconductors may explain the silvery mirror-like appearance of many fish, recent research suggests.
More than 50 years ago, when the laser was a mere 5 years old, laser physicists dreamed of the development of an X-ray laser to expand the frontier of knowledge.
A research team led by North Carolina State University has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared (IR) range. This is the first ...
NASA's planet hunter, the Kepler space telescope, has captured the brilliant flash of an exploding star's shock wave—what astronomers call the "shock breakout" of a supernova—for the first time in visible light wavelengths.
A new development from Northwestern University's Manijeh Razeghi could be another tool for protecting our borders.
This composite image shows an infrared view of Saturn's moon Titan from NASA's Cassini spacecraft, acquired during the mission's "T-114" flyby on Nov. 13, 2015.
The realization of photonic chips is a long–sought research goal. Surface plasmon polariton devices and circuits, which bridge the gap between integrated photonics and microelectronic technologies, are promising candidates ...
Seyfert galaxies are similar to spiral galaxies except that they have extraordinarily prominent, bright nuclei, sometimes as luminous as 100 billion Suns. Their huge energies are thought to be generated as matter falls towards ...
A revolutionary new type of laser developed by the University of Adelaide is promising major advances in remote sensing of greenhouse gases.
A UConn researcher has developed a light-harvesting antenna that could double the efficiency of existing solar cell panels and make them cheaper to build.
