Tuning terahertz transmission

The ability to manipulate light on a subwavelength-scale could lead to a revolution in photonic devices such as antennas, solar panels, and even cloaking devices. Nanotechnology advances have made this possible through the ...

Harnessing photonics for at-home disease detection

In the not-too-distant future, people may have a simple device that monitors and reports health indicators, identifies even trace amounts of undesirable biomarkers in the blood or saliva and serves as an early warning system ...

Mass manufacturing of metasurfaces

The mass production of flat optical devices with sub-wavelength structures could soon be a reality, thanks to a metasurface fabrication technique developed by researchers at A*STAR.

'Meta-mirror' reflects sound waves in any direction

Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking ...

Next-generation optics in just two minutes of cooking time

Optical circuits are set to revolutionize the performance of many devices. Not only are they 10 to 100 times faster than electronic circuits, but they also consume a lot less power. Within these circuits, light waves are ...
