A chip‑scale laser array with integrated beam shaping enables ultrafast, energy‑efficient optical wireless links for indoor ...

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

CU Boulder postdoc Catherine Saladrigas is helping bring high-resolution imaging into miniature microscopes for neuroscience research. In a promising leap forward for imaging, Saladrigas and a team of ...

Bright background light can do more than clutter a quantum experiment. It can wash out the very features that make quantum ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Want to call someone a quick-thinker? The easiest cliché for doing so is calling her a computer – in fact, “computers” was the literal job title of the “Hidden Figures” mathematicians who drove the ...
