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 ...

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 ...

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is steered ...
