Using SLAC's instrument for ultrafast electron diffraction (MeV-UED), one of the lab's world-leading tools for ultrafast science, researchers discovered how an ultrathin material can circularly polarize light. This discovery sets up a promising approach to manipulate light for applications in optoelectronic devices.
While taking snapshots with the high-speed "electron camera" at the Department of Energy's SLAC National Acceleratory Laboratory, researchers discovered new behavior in an ultrathin material that offers a promising approach to manipulating light that will be useful for devices that detect, control or emit light, collectively known as optoelectronic devices, and investigating how light is polarized within a material. Optoelectronic devices are used in many technologies that touch our daily lives, including light-emitting diodes (LEDs), optical fibers and medical imaging.
