Not only is its luminance level several orders of magnitude higher than liquid-crystal-device and organic light-emitting diode displays, but a new video-capable emissive indium...
Scientists at Nichia Corp. (Anan, Japan) have demonstrated the first electrically pumped indium gallium nitride/gallium nitride (InGaN/GaN)-based blue- and green-emitting vertical...
High-risk, high-payoff research is DARPA's charter. The agency tackles a wide range of photonics challenges, including building high-energy lasers compact enough to get off the...
The often overlooked ensquared and encircled energy (EE) test method-a quantification of the fraction of optical energy present in an aperture for an optics system-can provide...
The latest generation of research-grade imaging and spectroscopy ICCD cameras uses novel software-customizable approaches to signal readout management and intensifier gating, ...
Understanding the plastic optics production process and the material requirements of the application enables customers to incorporate plastic optics into designs that lower costs...
Both stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering (CARS) microscopy use light from a pump and probe laser beam scanned over tissue or a test sample...
Researchers at Wake Forest University (Winston-Salem, NC) and Fisk University (Nashville, TN) have analyzed the crucial role that electron and hole mobilities have in strontium...
Compared to conventional waveform-digitizing altimeters or laser time-of-flight lidar techniques, photon-counting lidar is a more efficient technique as it requires only one detected...
Using scanning tunneling microscopy, researchers at the University of Illinois at Urbana-Champaign (Urbana, IL) have observed the subnanometer structure of amorphous silicon (...
While progress is being made in the development of semiconductor UV lasers and LEDs, their external quantum efficiency remains low. One potential solution could be application...
Researchers at the Leibniz Universität Hannover (Hannover, Germany) have achieved a new efficiency high for the frequency doubling of continuous-wave laser light.
Researchers at the Max Planck Institute for the Science of Light (Erlangen, Germany) have developed the first soft-glass, hollow-core photonic-crystal fiber to offer singlemode...
Solar simulators—instruments that simulate the irradiance and spectral output of our own Sun in order to test photovoltaic solar cells in indoor environments—are not created equal...
Infrared (IR) surveillance systems are used in satellites that survey the earth's surface to carry out environmental analysis—for example, to monitor marine pollution or study...
Although the process of turning graphite oxide into a supercapacitor turns out to be very simple, it was not immediately obvious to the scientific community until Rice University...
In electrowetting, an applied voltage changes the wetting angle of a liquid; the phenomenon is used in liquid lenses and, with pigmented fluids, in liquid displays.
A step-index multimode fiber co-doped with phosphorus and germanium is an excellent sensor for gamma-radiation doses; its low dependence on dose rate makes it potentially useful...
