Journal ArticleDOI
Two‐dimensional electro‐optic imaging of THz beams
TL;DR: In this article, a novel electro-optic sampling system for real-time terahertz (THz) imaging applications was proposed, which achieved time-resolved images of pulsed far-infrared radiation emitted from an unbiased GaAs wafer.
Journal ArticleDOI
Magnetic switching of THz beams
TL;DR: In this article, the authors demonstrate the use of a magnetic field to switch and control the direction and polarization of a THz beam radiated from a semiconductor emitter, and demonstrate that the magnetic field can also be used to control the polarization of the beam.
Book ChapterDOI
Electro-Optic Imaging of THz Beams
TL;DR: In this article, an alternative method for real-time terahertz (THz) imaging applications was proposed by illuminating an electro-optic crystal with a THz beam and an optical readout beam, then detecting the optical beam with a linear diode array or a CCD camera.
