Australian research helping self-driving cars get on the road

Researchers from the Australian National University and TMOS, an Australian Research Council Centre of Excellence, have developed a highly sensitive self-powered single photon detector that could be used to make self-driving cars safer and more energy efficient. A fast, single-photon Light Detection And Ranging (LIDAR) is far more sensitive than other forms of LIDARs, allowing […]

Generating entangled photons with nonlinear metasurfaces

Illustration of a metasurface generating pairs of photons (shown as spheres).  The photon entanglement can be varied by changing the pump beam (shown in red). Illustration by Andrei Komar & Matthew Parry. Subhed: A new method for generating quantum-entangled photon pairs employs nonlinear metasurfaces to enhance and tailor photon emissions—an important step towards creating miniaturized […]

Reimagining medical diagnostics in developing countries: meta-optics offers a new way to look inside cells

Developing countries face many challenges in the fight against infectious diseases. One of these is the lack of access to medical diagnostic tools. This is considered a key reason why malaria and tuberculosis are still two of the leading causes of death in sub-Sahara Africa and parts of Asia. In order to address issue of […]
