  • Abstract
    Summary form only given. Terahertz (THz) radiation has attracted a lot of attentions due to its fascinating potential applications. Wavefront modulation of the THz radiation will benefit the applications of THz imaging and communication. We propose a novel approach to actively modulate the wave-front of the THz radiation based on the THz hologram formed with photon-generated carriers. The diffracted THz beam will come into special amplitude and phase distribution. Experiment results demonstrate the validity of this new method.
