Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

However, this new study challenges that notion. "We have demonstrated that by using optical vortex beams—light beams that carry angular momentum—we can precisely control how an electron is ...

The "Where the Light Gets In" exhibit features illuminated "spears" piercing 43 trees. The display is meant to be a "death ritual" acknowledging the trees' removal for new construction. A public ...

Multiple people spotted a mysterious beam of light in the sky last week. The “red flare”, as many described it, was spotted by people in Houston and other places throughout the world.

Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive lasers or commercial-grade equipment; this video by [W1VLF ...

The most widely used such devices, known as Mach-Zehnder interferometers, work by splitting a beam of light down two paths to toggle its output. Despite their widespread use, Mach-Zehnder ...

Scientists have found a new way to navigate beams of light through dynamic scattering media, such as the turbulent atmosphere or living tissue. A team of physicists, led by Professor David ...
