摘　　要：In this work, we experimentally demonstrate an image information transfer between two channels by using slow light based on electromagnetically induced transparency（EIT） in a solid. The probe optical image is slowed due to steep dispersion induced by EIT. By applying an additional control field to an EIT-driven medium, the slowed image is transferred into two information channels. Image intensities between two information channels can be controlled by adjusting the intensities of the control fields. The similarity of output images is further analyzed. This image information transfer allows for manipulating images in a controlled fashion, and will be important in further information processing.In this work, we experimentally demonstrate an image information transfer between two channels by using slow light based on electromagnetically induced transparency（EIT） in a solid.
