Engineers bend light to enhance wavelength conversion

Electrical engineers from the UCLA Samueli School of Engineering have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing ...

Light-generating transistors to power labs on chips

(PhysOrg.com) -- What started out as 'blue-sky' thinking by a group of European researchers could ultimately lead to the commercial mass production of a new generation of optoelectronic components for devices ranging from ...

'Metasurfaces' to usher in new optical technologies

(Phys.org) —New optical technologies using "metasurfaces" capable of the ultra-efficient control of light are nearing commercialization, with potential applications including advanced solar cells, computers, telecommunications, ...

The art of invisibility and the perfect cat's eye

(PhysOrg.com) -- In recent years scientists have explored the impossible by developing invisibility or 'cloaking' devices, but can the same technology also help make things more visible?

Ingestible medical devices can be broken down with light

A variety of medical devices can be inserted into the gastrointestinal tract to treat, diagnose, or monitor GI disorders. Many of these have to be removed by endoscopic surgery once their job is done. However, MIT engineers ...

Storing information with light

New photo-ferroelectric materials allow storage of information in a non-volatile way using light stimulus. The idea is to create energy efficient memory devices with high performance and versatility to face current challenges. ...

Using technology to detect hidden threats

Soldiers in combat have to constantly scan their surroundings for improvised explosive devices (IEDs), a signature weapon of modern warfare. These homemade bombs are often hidden—nestled in bushes, buried underground, or ...
