Abstract
We present a novel technology to dynamically control the wave front of the terahertz (THz) beam with photo-generated carriers. The computer generated hologram is projected onto a silicon wafer by a conventional optical spatial light modulator. The photo-generated carriers on the silicon surface will from a hologram to modulate the wave front of the input THz beam. Some special field distributions and vortex beams are generated using this method. This technology is broadband, structure free, tunable, and all-optical controllable. It will provide numerous possible applications in future THz imaging and communication systems.
