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 ...

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.

Specifically, one light beam promotes the formation of the polymeric material, while another beam halts the reaction. The research is published in Advanced Functional Materials. This chemical ...

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 ...
