A type of laser beam, developed by a team at the University of Central Florida (UCF), does not follow the classical laws of refraction and could offer new opportunities for shaping the flow of light beams used for optical communications and laser applications. Normally, light slows down when it passes through a dense material. The new class of laser beams, called spacetime wave packets, can be arranged to not change speed at all, or even to speed up in denser materials. “As such, these pulses of light can arrive at different points in space at the same time,” professor Ayman...Read full articleRelated content from Photonics MediaARTICLESLiquid Crystal-Based Devices Manipulate Light with Flat Optics to Uncover Hidden ImagesAn ancient optical illusion has been updated using the flat optics of today to create a device that reveals a hidden image when light is shined on it.
