“…It was discovered that current-biased HTSCs also radiate THz pulses through the illumination of femtosecond optical pulses [9][10][11][12][13][14][15][16][17][18][19]. Tonouchi et al revealed detailed characteristics of THz emission from HTSCs excited with FS laser pulses, as shown in figure 1, which is a typical waveform of a THz wave emitted from a YBCO thin film dipole antenna.…”

“…A semiconductor photoconductive switch excited by femtosecond (FS) laser pulses is generally used for THz time-domain spectroscopy (THz-TDS) as a THz source and a detector [6][7][8]. On the other hand, a superconducting photoswitch with a high-T c superconductor (HTSC) thin film has also been studied as a unique superconducting THz source or an ultrafast photoswitching device [9][10][11][12][13][14][15][16][17][18]. THz radiation is generated by the ultrafast modulation of the supercurrent in HTSCs excited by FS laser pulses.…”

Recent progress in terahertz technology has enabled precise investigation of the ultrafast dynamics of excited carriers, nonequilibrium state and nonlinear response of superconductors, resulting in the proposal of novel optoelectronic device applications based on such ultrafast perturbation of supercarriers in the terahertz frequency region. In this paper, we focus on exploratory research in the field of superconductor terahertz science and technology, and present a review of superconducting terahertz sources and the response of superconductors excited by ultrashort electromagnetic pulses, including optical pulses and high-intensity THz pulses.

The origin of photogenerated terahertz radiation pulse emitted from current-biased superconducting YBa 2 Cu 3 O 7Ϫ␦ thin films excited by femtosecond optical laser pulses is delineated. By investigating the performance of the transient terahertz radiation generated under different operating parameters, pulse reshaping in the measured terahertz electric field caused by the kinetic inductance of the superconducting charge carriers is identified. After recovering the original wave forms of the emitted terahertz pulses, the transient supercurrent density directly correlated to the optically excited quasiparticle dynamics is obtained. A fast decreasing component of about 1.0 ps and a slower recovery process with a value of 2.5 ps are unambiguously delineated in the optically induced supercurrent modulation. The radiation mechanism of the transient terahertz pulse related to nonequilibrium superconductivity is discussed.
