The method helps discovering the most efficient lamps, which may save billions in lighting costs in the future.
Scientists have created the world's thinnest lens, one two-thousandth the thickness of a human hair, opening the door to flexible computer displays and a revolution in miniature cameras.
Researchers from FOM, the University of Amsterdam, the Delft University of Technology and the University of the Algarve have discovered that when light hits germanium nanocrystals, the crystals produce 'bonus electrons'. ...
A tiny mirror could make a huge difference for scientists trying to understand what's happening in the micron-scale structures of living cells.
By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.
The most common kind of light bulb in the United States—the incandescent—is only about 5 percent efficient. The phosphorescent organic light-emitting diode, on the other hand, makes light out of 100 percent of the electricity ...
Researchers from the California NanoSystems Institute at UCLA have created a new technique that greatly enhances digital microscopy images.
Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. Researchers at EPFL have managed to generate such lasers using a simple and inexpensive method.
How can we constantly monitor the stability of a bridge or detect a leak in a gas pipeline in real time? A method based on optical fibers has become the norm in recent years. By carefully measuring the path of light in fibers ...
(Phys.org) —About the size of a stapler, this new handheld device developed at EFPL is able to test a large number of proteins in our body all at once-a subtle combination of optical science and engineering.
