Far-infrared time-domain spectroscopy with terahertz beams of dielectrics and semiconductors
Grischkowsky, D.; Keiding, Soren; van Exter, Martin; Fattinger, Ch. (Optical Society of America, 1990-10)Using the method of time-domain spectroscopy, we measure 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, ... -
High-brightness terahertz beams characterized with an ultrafast detector
van Exter, Martin; Fattinger, Ch.; Grischkowsky, D. (AIP Publishing, 1989-07-24)We have significantly improved the emission and detection of electromagnetic beams of single-cycle 0.5 THz pulses, through the use of new dipolar antenna structures. The frequency response was extended to well beyond the ... -
Observation of electromagnetic shock waves from propagating surface-dipole distributions
Fattinger, Ch.; Grischkowsky, D. (American Physical Society, 1989-06-19)We have directly measured the time-dependent electromagnetic shock wave generated by an electric surface-dipole distribution propagating faster than the phase velocity in the underlying dielectric substrate. The results ... -
Point source terahertz optics
Fattinger, Ch.; Grischkowsky, D. (AIP Publishing, 1988-10-17)We demonstrate an ultrafast 10 micro-m sized, electric dipole source of terahertz radiation closely coupled to a 1 cm spherical mirror. This optical approach has the advantages of subpicosecond response times with essentially ...
