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 ...
When AI and optoelectronics meet: Researchers take control of light properties
Using machine-learning and an integrated photonic chip, researchers from INRS (Canada) and the University of Sussex (UK) can now customize the properties of broadband light sources. Also called "supercontinuum", these sources ...
Deep learning for glaucoma detection
Glaucoma is the second leading cause of blindness in the world, impacting approximately 2.7 million people in the U.S alone. It is a complex set of diseases and, if left untreated, can lead to blindness. It's a particularly ...
Trapping atoms, not space ships, with tractor beams
University of Adelaide researchers have delved into the realm of Star Trek and created a powerful tractor beam – or light-driven energy trap – for atoms.
Tiny camera lens may help link quantum computers to network
An international team of researchers led by The Australian National University (ANU) has invented a tiny camera lens, which may lead to a device that links quantum computers to an optical fibre network.
New colour-generation mechanism discovered in 'rainbow' weevil
Researchers from Yale-NUS College and the University of Fribourg in Switzerland have discovered a novel colour-generation mechanism in nature, which if harnessed, has the potential to create cosmetics and paints with purer ...
Using fibre-optic cables to detect earthquakes
Fibre-optic cables can be used to detect earthquakes and other ground movements. The data cables can also pick up seismic signals from hammer shots, passing cars or wave movements in the ocean. This is the result of a study ...
In physics, a famous paradox that hangs by a thread of light
Imagine a metal bar that has been heated at one end. Instead of the heat gradually spreading over its entire length, the bar eventually becomes hot again at the place where it was originally. The fact that, paradoxically, ...
Ultrasound imaging needle to transform heart surgery
Heart tissue can be imaged in real-time during keyhole procedures using a new optical ultrasound needle developed by researchers at UCL and Queen Mary University of London (QMUL).
