Slow light is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. Slow light occurs when a propagating pulse is substantially slowed by the interaction with the medium in which the propagation takes place. Group velocities below c were known to be possible as far back as 1880, but could not be realized in a useful manner until 1991, when Stephen Harris and collaborators demonstrated electromagn… WebbDownload free stock video footage featuring IKEA logo closeup - Slowly backward moving aerial close to Ikea logo on warehouse - Sun lighting up logo and warehouse with dark background - Norway.
