Power Combining Technology in Three-way Terahertz Photoconductive Antenna
摘要
针对单个光导天线功率容量有限的问题, 采用光导天线功率合成技术研究高功率、超宽带的太赫兹辐射方法。通过构建三路光导天线功率合成系统, 以500 μm孔径的偶极子光导天线为对象, 进行了功率合成技术研究。结果表明: 当三路500 μm孔径的偶极子光导天线产生太赫兹的光程差一致时, 合成后的时域光谱峰值最大, 时域相干度达90.6%, 提高了太赫兹输出的功率。
Abstract
For the limited power capacity problem of single photoconductive antenna, we use photoconductive antenna power combining technology to research high power and ultra-broadband terahertz radiation. By constructing a power combining system of three-way photoconductive antenna, using 500 μm aperture dipole photoconductive antenna as the object, we studied the power combining technology. When the optical path differences of terahertz emitted by three-way 500 μm aperture photoconductive dipole antenna are the same, the power combined time-domain spectral reaches to maximum peak, the degree of temporal coherence up to 90.6%, the output power of terahertz is improved efficiently.
