In this paper, we observed the nonlinear response on high temperature superconducting thin film YBaCu3O7-δ (YBCO) and low temperature superconducting thin film niobium nitride (NbN) by the use of intense single-cycle terahertz (THz) pulses with photon energies well below the superconductors energy gap.Meanwhile, we also demonstrated the nonlinear response of superconducting metamaterial in the terahertz regime, which is comprised of an array of sub-wavelength split-ring resonators (SRRs) made from superconducting NbN film.
