A new research by Stanford scientist demonstrate a new approach to slow down light so that photons have more chances to interact with other materials, opening a door for new applications such as LiDAR, LiFi and AR/VR. The research paper was published in Nature Nanotechnology on August 17, 2020. To slow down light, the Stanford researchers structured ultrathin silicon chips into nanoscale bars to resonantly trap light and then release or redirect it later. The approach is like creating an echo chamber to hold onto sound and direct it. These "high-quality-factor&quo...
