Abstract

Terahertz radiation has been studied extensively both experimentally and theoretically within the past decades. A number of methods have been developed to generate terahertz radiation using ultra-short laser pulses, including photoconductive effect, optical rectification, and so on. The photoconductive effect has been utilized to generate THz radiation from a piece of semiconductor with antenna structure. The bias electric field between the electrodes of photoconductor is limited by the breakdown field of the semiconductor. In order to enhance the THz radiation power, the distribution of electric field on the surface of the substrate is simulated and the relationship between the geometrical structure of antenna and bias electric field is analyzed. The results show that the bow-tie antenna works more safely than other antennas under the same condition, and the breakdown risk of the PC antenna is reduced and the capability of resistance to voltage is improved.
