介绍了由在单晶氧化锌（ZnO）上制备的光电导天线产生的太赫兹（THz）辐射。在高于800 V/cm的偏置电压下，太赫兹辐射功率达到饱和，所获得的光谱延伸至1太赫兹。此外，发现氧化锌在可见光、近红外、中红外和太赫兹频率区域具有高度的透明性。这里所描述的结果将明确揭示使用氧化锌作为集成有源光学材料的前景。（c）2005美国物理学会
Terahertz (THz) radiation generated from photoconductive antenna fabricated on a single crystal zinc oxide (ZnO) is presented. The THz-radiation power is saturated at bias voltages above 800 V/cm and the obtained spectrum extends up to 1 THz. Moreover, ZnO is found to be highly transparent in the visible, near-infrared, mid-infrared and THz frequency regions. The results depicted here will categorically unravel the prospects of using ZnO as a material for integrated active optics. (c) 2005 American Institute of Physics.
