Optical beam steering based on electromagnetically induced transparency
MetadataShow full item record
We propose a scheme that provides all-optically-controlled steering of light beam. The system is based on steep dispersion of a coherently driven medium. Using the eikonal equation, we study the steering angle, the spread of the optical beam, and the limits set by residual absorption of the medium under conditions of electromagnetically induced transparency. Implementation of another scheme for ultrashort pulses is also discussed.
