摘要

提出了一种基于光导天线阵列的紧凑连续可调谐太赫兹源的新方案。窄带太赫兹辐射是由亚皮秒光导天线阵列的延时宽带辐射叠加产生的。通过2.5×10 mm2光导天线阵列原型，我们演示了平均功率为8 μW，辐射带宽为0.05 THz，调谐范围为0.65-1.4 THz。

High-power tunable terahertz generation based on photoconductive antenna arrays

A new scheme for a compact, continuously tunable terahertz source based on photoconductive antenna arrays is presented. Narrowband terahertz radiation is generated by superposition of time-delayed wideband radiations from an array of sub-picosecond photoconductive antennas. We demonstrate an 8 μW average power, radiation bandwidth of 0.05 THz, and a tuning range of 0.65–1.4 THz, through a 2.5×10 mm2 photoconductive antenna array prototype.
