摘要：
Emission of terahertz (THz) radiation as a result of optical rectification of intense femtosecond laser pulses on chiral metamaterials has been observed. The chiral metamamaterials has simplified fabrication design but still capable to exhibit different refractive index for each circular polarization. Nonlinear response of metamaterials was observed by terahertz emission spectroscopy. The result plot clearly shows that the terahertz signal is sufficiently fit with a square of laser power. The phenomenon can be referred as optical rectification and can be exploited for the development of new THz sources.
