Optical clocks are so accurate that it would take an estimated 20 billion years—longer than the age of the universe—to lose or gain a second. Now, researchers in the U.S. led by Jun Ye's group at the National Institute ...
Optical vortices, characterized by a helical phase front and doughnut-shaped intensity distribution, contribute to a broad range of applications, from microscopy to optical communications. And applications for optical vortices ...
