Journal ArticleDOI
Far-infrared time-domain spectroscopy with terahertz beams of dielectrics and semiconductors
TL;DR: In this paper, the authors measured the far-infrared absorption and dispersion from 0.2 to 2 THz of the crystalline dielectrics sapphire and quartz, fused silica, and the semiconductors silicon, gallium arsenide, and germanium.
Journal ArticleDOI
Generation and detection of terahertz pulses from biased semiconductor antennas
TL;DR: In this article, a simple model based on the Drude-Lorentz theory of carrier transport was proposed to account for the details of the ultrashort terahertz pulses radiated from small photoconductive semiconductor antennas.
Journal ArticleDOI
THz Spectroscopy of Liquid H 2 O and D 2 O
TL;DR: In this paper, the dielectric response of liquid was measured and analyzed using a Debye model with a fast and slow decay time by shifting the temperature scale for the slow decays of liquid.
Journal ArticleDOI
THz reflection spectroscopy of liquid water
TL;DR: In this paper, an experimental technique based on ultrashort electromagnetic pulses (THz pulses) was employed for fast and reliable data of both index of refraction and absorption coefficient for highly absorbing liquids.
Journal ArticleDOI

TL;DR: The supercontinuum generation in a highly nonlinear photonic crystal fiber with two closely lying zero dispersion wavelengths is demonstrated, which has high spectral density and is extremely independent of the input pulse over a wide range of input pulse parameters.
