Experimental time-domain study of THz signals from impulse excitation of a horizontal surface dipole
(AIP Publishing, 1999-03-22)
Using optoelectronic techniques with sub-ps resolution, we have characterized the electric-field time-domain response from an impulsively excited, micron-sized dipole antenna on a dielectric surface. When detected by an ...
Measurements of the THz absorption and dispersion of ZnTe and their relevance to the electro-optic detection of THz radiation
(AIP Publishing, 1999-06-07)
Via THz time-domain spectroscopy, we have measured the absorption and index of refraction of single-crystal (110) ZnTe from 0.3 to 4.5 THz. We find that the absorption is dominated by two lower-frequency phonon lines at ...
