Designing materials that steer light is a slow kind of trial and error. Each candidate structure must be tested in computer ...

Researchers at Chalmers University of Technology have developed a machine learning system that learns ...

Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a ...

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

The field of underwater optical communication is undergoing rapid transformation as researchers seek to address the physical limitations imposed by dynamic ...

It’s sometimes easy to forget that the light in the sky is an actual star. With how reliable it is and how busy we tend to be as humans, we can take that incredible fact and stow it away and largely ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

Figure 1. Working principle of the conventional and novel pancake optics systems. (a) configuration of the conventional pancake optics. (b) polarization conversion process in the conventional pancake ...

What is Non-Hermitian Physics? Non-Hermitian physics is a rapidly growing field that deals with open quantum systems that exchange energy and information with their environment. Unlike closed systems ...

Attosecond photon pulses are used to investigate dynamical processes in matter with unprecedented temporal resolution (Credit: iStock/7io). Experimental attosecond science is built around the ability ...
