Time was when the buying and reading of a new book was quite simple. If you read a promising review of a recently published book, a quick phone call to your local bookseller would...
Building on earlier work that described breakthrough wafer-level-packaging developments related to miniature CMOS imagers with 1.7 µm pixel pitch, researchers at the Fraunhofer...
Imagine converting the Sun's energy to electricity without the need for expensive semiconductor materials or the usual absorption-exciton-drift-current conversion steps. This ...
The generation of "slow light" (in which the group velocity of light in a material is slowed down substantially due to a specially tailored dispersion profile) is potentially ...
Scientists at OFS Denmark (Brøndby, Denmark) and OFS Labs (Somerset, NJ) have developed a dispersion-compensating optical fiber with a factor of 5.0 improvement in figure of merit...
The secret to the shimmering brilliance of two beetles that shine naturally with silver and gold colors has been unlocked by researchers at Universidad de Costa Rica (San José...
For applications such as on-chip and intrachip optical communications, electrically pumped lasers with compact size, low power dissipation, and low-threshold operation are needed...
Germanium (Ge)-on-silicon photodetectors operate successfully in the telecommunications wavelength ranges centered at 1310 nm and 1550 nm (the C- and L-bands), respectively; however...
A see-through photovoltaic (PV) module for window-integrated use developed at the Nagaoka University of Technology (Niigata, Japan) contains a low-concentration prism concentrator...
Concocting a green-light-emitting fiber laser has meant taking the output of an IR-emitting fiber laser (for example, around 1060 nm) and frequency doubling it. Researchers at...
Percussion drilling with nanosecond laser-pulse bursts, instead of single nanosecond pulses, has advantages for metal machining, according to researchers from Multiwave Photonics...
Competing nonlinear processes have limited pulsed fiber lasers to modest peak powers, restricting application possibilities. But a new pulsed laser overcomes this barrier through...
