摘要

提出了一种基于光导光电混合器/天线单元的新型阵列结构，并对其作为连续波太赫兹源的辐射特性进行了全面研究。在阵列配置中使用集成的光电转换器/天线元件增加了可用的太赫兹功率，而每个阵列元件都在临界吸收光功率水平下工作。结果表明，该结构可获得数微瓦的太赫兹辐射功率，其主要受限于相应波长的可用激光功率。

CW photoconductive photomixer/antenna array source for THz applications

A new array structure based on the photoconductive photomixer/antenna elements is proposed and its radiation characteristic as a CW terahertz source is fully investigated. Employing the integrated photomixer/antenna elements in an array configuration increases the available THz power, while each of the array elements operates under the critical absorbed optical power level. It is shown that several microwatt THz radiation power is achievable from the proposed structure, and it is mainly limited by the available laser power at the corresponding optical wavelength.
