Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international collaborators, have developed two complementary methods that could make quantum ...

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

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

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

Can quantum optics be used for practical applications? A lot depends on whether a large number of photons can be gathered in quantum state. Among all quantum systems, photons are known for their weak ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...
