Abstract :
Terahertz (THz) radiation emission from photoconductive antenna fabricated on single crystal ZnO is presented. Results reveal that ZnO is highly transparent in the visible, near-infrared, mid-infrared and THz frequency regions. These characteristics will open up the possibility of using ZnO as material for the realization of integrated active optics.
