TL;DR: In this article, a material deposited by molecular beam epitaxy at low substrate temperatures using Ga and As4 beam fluxes has been used as the active layer for a high-speed photoconductive optoelectronic switch.
Journal ArticleDOI
Generation of high-power sub-single-cycle 500-fs electromagnetic pulses.
TL;DR: The pulse energy of the far-infrared radiation is found to be a quadratic function of bias field and a nonmonotonic function of laser intensity.
Journal ArticleDOI
Terahertz emission from electric field singularities in biased semiconductors
TL;DR: This work uses electric field singularities in metal-semiconductor microstructures to generate efficient THz radiation and electrical transients and reports on the generation process in a number of material systems.
Journal ArticleDOI
Interferometric characterization of 160 fs far-infrared light pulses
TL;DR: In this article, the first interferometric characterization of freely propagating, sub-picosecond, far-infrared (FIR) light pulses was reported. FIR light was generated via short pulse photoexcitation of a semi-insulating InP wafer.
Journal ArticleDOI
Propagation model for ultrafast signals on superconducting dispersive striplines
TL;DR: In this paper, the effects of modal dispersion and the complex surface conductivity of the superconductor are demonstrated, with the conclusion that it is necessary to incorporate both phenomena for accurate modeling of transient propagation in strip transmission lines.
