Brief reflections from a plasma mirror

When a dense sheet of electrons is accelerated to almost the speed of light, it acts as a reflective surface. Such a 'plasma mirror' can be used to manipulate light. Now an international team of physicists from the Max Planck ...

Covert infrared image encoding—hiding in plasmonic sight

Plasmonic materials can uniquely control the electromagnetic spectrum due to nano-scale surface architecture. Recent advances in nanotechnology and materials science and their combined capacity to develop controlled geometries ...

New methods could improve, expand 3-D imaging using X-rays

Researchers report two new approaches to producing three-dimensional (3-D) images using X-rays that could improve disease-screening, study of very fast processes and enable analysis of the properties of materials and structural ...

Changing color of light using a spatiotemporal boundary

A KAIST team developed an optical technique to change the color (frequency) of light using a spatiotemporal boundary. The research focuses on realizing a spatiotemporal boundary with a much higher degree of freedom than the ...

First study of terahertz radiation in liquids

A research team from ITMO University and the University of Rochester (U.S.) conducted a study on the formation of terahertz radiation in liquids. Previously, the generation of such radiation in a liquid medium was considered ...

Scientists develop minimally invasive brain probe

Researchers from the Leibniz Institute of Photonic Technology (Leibniz-IPHT) in Jena and the University of Edinburgh have succeeded in using a hair-thin fiber endoscope to gain insights into previously inaccessible brain ...

Scientists obtain a hexagonal modification of silicon

A team of scientists from Lobachevsky University (Nizhny Novgorod, Russia) has obtained a material with a new structure for applications in next-generation optoelectronics and photonics. This material is one of the hexagonal ...

Photonic radiation sensors survive huge doses undamaged

Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be used in high-radiation environments and to advance important medical, ...

New scientific concept for a Star Wars-like tractor beam

Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The ...

Paving the way: An accelerator on a microchip

Electrical engineers in the accelerator physics group at TU Darmstadt have developed a design for a laser-driven electron accelerator so small it could be produced on a silicon chip. It would be inexpensive and with multiple ...

Millimetre waves for the last mile

Reseachers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the "last mile" up to the internet ...
