In a pair of recent papers, two different research groups have brought the unique properties of ultrathin dielectric metasurfaces to bear on some problems in quantum information and communications. In one demo, researchers in Australia, Taiwan and the United States...

The smallest amount of light you can have is one photon, so dim that it’s pretty much invisible to humans. While imperceptible, these tiny blips of energy are useful for carrying quantum information around. Ideally, every quantum courier would be...

Simple, efficient and fast uncooled device operating at 12.2µm wavelength looks suitable for realization of future on-chip detector array....

This instrument combines four optical microscopy technologies to image live cancer cells in 4D....

This development provides an exciting opportunity to perform 3D imaging on samples that are very difficult to image with conventional methods....

This technique could be used to design high-resolution cameras in other frequency ranges, which could be incorporated into technology for collision sensors, body scanners, or ultrafast radars for self-driving cars....

Technique could be used to scale-up self-assembled materials for use as optical sensors, color displays, and light-guided electronics....

Researchers applied the fluorescent probe to a sputum sample collected from a tuberculosis-positive patient; the bright green shows where there is live tuberculosis....

AI tools from DeepMind were able to interpret OCT retinal scans rapidly and accurately....

Researchers developed a handheld adaptive optics scanning laser ophthalmoscope that weighs about the same as a large mobile phone. It can be used to image individual photoreceptors in people....
