First single-crystal organometallic perovskite optical fibers

Due to their very high efficiency in transporting electric charges from light, perovskites are known as the next generation material for solar panels and LED displays. A team led by Dr. Lei Su at Queen Mary University of ...

The invention of a flexible endoscope thinner than a needle

If you are used to getting regular health checkups, you might be familiar with endoscopes. The endoscope is an imaging device consisting of a camera and a light guide attached to a long flexible tube. It is particularly useful ...

'Plug-and-play' plasmonic metafibers for ultrafast fiber lasers

Integrating plasmonic metasurfaces on optical fiber tips forming so-called metafibers enriches the functionalities of an ordinary optical fiber, yielding a variety of advanced applications such as planar waveshaping, super-resolution ...

Scientists twirl liquid light into time-periodic cluster

Researchers from Skoltech, the University of Iceland, and the University of Southampton have demonstrated the formation of an odd never-before-seen entity from the realm of quantum physics: a cluster of optical vortices with ...

Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

Quantum cryptography: Making hacking futile

The Internet is teeming with highly sensitive information. Sophisticated encryption techniques generally ensure that such content cannot be intercepted and read. But in the future high-performance quantum computers could ...

New glass-ceramic emits light when under mechanical stress

Researchers have created a new glass-ceramic that emits light in response to mechanical stress, a property known as mechanoluminescence. With further development, the new material could be used to create a light source that ...

Existing fiber optic cables can monitor whales

A new study demonstrates for the first time that the same undersea fiber optic cables used for internet and cable television can be repurposed to tune in to marine life at unprecedented scales, potentially transforming critical ...
