摘要

光导天线是目前应用最广泛的太赫兹(THz)波产生和探测器件，但其产生功率非常低。人们对如何提高辐射太赫兹功率进行了一些研究，发现在某一点激发是提高效率的一种实用方法。本文提出了一种理论来支持这一观点。分析了光导天线在某一点激发能产生比全间隙激发更高太赫兹功率的原因。

A Theory of How to Improve the Radiation of the Photoconductive Antenna

The photoconductive antenna is the most widely used device to generate and detect the terahertz (THz) wave but it has a limitation that the generated power is very low. There have been some investigations into how to increase the radiated THz power and it was found that to excite at a point is a practical method to improve the efficiency. In this paper, a theory is developed to support this idea. The analysis shows the reason why excitation at a point can generate higher THz power than the whole gap excitation of photoconductive antenna.
