The original all-electronic, open-access optics journal, Optics Express (OpEx) is known for its rapid time to publication and high Impact Factor. OpEx publishes peer-reviewed articles that emphasize scientific and technology innovations in all aspects of optics and photonics.
NIST therapy for ultraviolet laser beams: Hydrogen-treated fibers
To make a better optical fiber for transmitting laser beams, the first idea that comes to mind is probably not a nice long hydrogen bath.
Graphene surfaces on photonic racetracks
In an article published in Optics Express, scientists from The University of Manchester describe how graphene can be wrapped around a silicon wire, or waveguide, and modify the transmission of light through it.
Zoomable holograms pave the way for versatile, portable projectors
Imagine giving a presentation to a roomful of important customers when suddenly the projector fails. You whip out your smartphone, beam your PowerPoint presentation onto the conference room screen, and are back in business ...
Making smartphones smarter with see-through sensors
(Phys.org)—Your smartphone's display glass could soon be more than just a pretty face, thanks to new technology developed by researchers from Montreal and the New York-based company Corning Incorporated. The team has created ...
Telescopic contact lens could improve eyesight for the visually impaired
(Phys.org) —A team of engineers has designed a telescopic contact lens that can switch between normal and magnified vision by using slightly modified off-the-shelf 3D television glasses. The researchers, led by Joseph Ford, ...
Scientists develop compact medical imaging device
Scientists at the MIRA research institute, in collaboration with various companies, have developed a prototype of a handy device that combines echoscopy (ultrasound) with photoacoustics. Combining these two medical imaging ...
New camera system creates high-resolution 3-D images from up to a kilometer away
(Phys.org) —A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes the light to travel ...
New quantum-cascade laser operates at significantly higher temperatures than previously
For the observation of cold matter in the interstellar medium, astronomers need instruments for the detection of terahertz radiation. Specific high-resolution instruments are based on terahertz quantum-cascade lasers, but ...
Nanostructures triple organic solar cells efficiency
Princeton researchers have found a simple and economic way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.
Breaking the final barrier: Room-temperature electrically powered nanolasers
(Phys.org) —A breakthrough in nanolaser technology has been made by Arizona State University researchers.
