Cutting through fog with laser focus

Research from The University of Queensland aimed at controlling light in scattering materials, such as fog or biological tissues, will benefit future biomedical imaging and telecommunications.

Field-resolved infrared spectroscopy of biological systems

Scientists at the Laboratory for Attosecond Physics have developed a unique laser technology for the analysis of the molecular composition of biological samples. It is capable of detecting minimal variations in the chemical ...

Flexible photonic crystal from liquid thin-film metasurface

Photonic crystals are predicted to be one of the wonders of the 21st century. In the 20th century, new understanding of the electronic band structure-the physics that determines when a solid conducts or insulates-revolutionized ...

Lasers learn to accurately spot space junk

Chinese researchers have improved the accuracy in detecting space junk in earth's orbit, providing a more effective way to plot safe routes for spacecraft maneuvers.

Large-area and flexible near-infrared light-emitting diodes

Infrared LEDs are useful for optical communications and covert illumination, and are commonly found in remote controls and security camera setups. They are generally small point sources, which limits their use if larger-area ...

New rules illuminate how objects absorb and emit light

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.

Electronics at the speed of light

A European team of researchers including physicists from the University of Konstanz has found a way of transporting electrons at times below the femtosecond range by manipulating them with light. This could have major implications ...

Using light to encrypt communications

Researchers of the UT found a new way to protect data from attacks with quantum computers. As they published today in New Journal of Physics. With quantum computers on the rise, we can no longer exclude the possibility that ...

Researchers produce first laser ultrasound images of humans

For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient's skin, sound waves generated by the probe travel through the skin, bouncing off muscle, fat, ...
