Quantum photonics involves a new type of technology that relies on photons, the elementary particle of light. These photons can potentially carry quantum bits of information over large distances. If the photon source could ...
Since the development of diffractive optical elements in the 1970s, researchers have increasingly uncovered sophisticated fundamental principles of optics to replace the existing bulky optical elements with thin and lightweight ...
Quantum optics, spintronics and diffraction-free imaging with low loss are among the technologies that may benefit from recently predicted effects in twisted bilayer photonic structures. The work takes inspiration from a ...
The destructive force of a tornado occurs due to the extremely high rotational speeds in its center, which is called a vortex. Surprisingly, similar effects are predicted for light that travels along an atomically smooth ...
Engineers at the McKelvey School of Engineering at Washington University in St. Louis have received federal funding for a rapid COVID-19 test using a newly developed technology.
Millions of people have been tested for the novel coronavirus, most using a kit that relies on the polymerase chain reaction (PCR). This sensitive method amplifies SARS-CoV-2 RNA from patient swabs so that tiny amounts of ...
A palette of colors on a silver plate: That is what the world's first color photograph looks like. It was taken by French physicist Edmond Becquerel in 1848. His process was empirical, never explained, and quickly abandoned. ...
High-repetition-rate pulsed lasers serve a wide range of applications, from optical communications to microwave photonics and beyond. Generating trains of ultrashort optical pulses commonly involves locking phases of longitudinal ...
Photonic cavities are an essential part of many modern optical devices, from laser pointers to microwave ovens. Just as we can store water in a tank and create standing waves on the surface of the water, we can confine light ...
Plasmon enhanced spectroscopy allows scientists to reach single molecule sensitivity and a lateral resolution even down to sub-molecular resolution. A major challenge for it to become a user-friendly analytical tool however ...
