APPARATUS FOR GENERATING TERAHERTZ WAVE AND METHOD FOR CONTROLLING TERAHERTZ WAVEFRONT USING THE SAME

摘要

The present invention relates to a terahertz wave generator capable of controlling a wavefront. The terahertz wave generating apparatus according to an embodiment of the present invention includes a photoconductive substrate and a plurality of unit elements for generating terahertz waves arranged in a two-dimensional array on the photoconductive substrate, and generating the terahertz wave The unit devices for use include a plurality of first electrodes arranged in the form of the two-dimensional array on the photoconductive substrate and individually connected to different first electrode pads among a plurality of first electrode pads, and the photoconductive substrate And one or more second electrodes formed thereon to face the first electrodes.
