Researchers at Aalto University have developed metasurfaces with extreme angle-asymmetric response. The surface reflections depend on the angle at which light hits it.
A research team led by The Australian National University (ANU) has invented a device that could be developed into ultra-sensitive cameras for security screening which would not require people to queue at airports.
Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency. Smart multiplexing techniques (multiple signal ...
Electromagnetic and optical nonlinear effects provide an important platform in a broad spectrum of technologies, including high harmonic generation, sum and difference frequency conversions, self-focusing, optical solitons, ...
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 ...
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 ...
Â鶹ÒùÔºicists 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 ...
Today's optical systems—from smartphone cameras to cutting-edge microscopes—use technology that hasn't changed much since the mid-1700s. Compound lenses, invented around 1730, correct the chromatic aberrations that cause ...
A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells "meta-atoms." ...
The next generation of electronic devices, ranging from personal health monitors and augmented reality headsets to sensitive scientific instruments that would only be found in a laboratory, will likely incorporate components ...
