Recent advances in terahertz imaging
We review recent progress in the field of terahertz “T-ray” imaging. This relatively new imaging technique, based on terahertz time-domain spectroscopy, has the potential to be the first portable far-infrared imaging spectrometer. We give several examples which illustrate the possible applications of this technology, using both the amplitude and phase information contained in the THz waveforms....
متن کاملBright terahertz sources
■ ■ What was terahertz science like in the early days? When I first became involved in terahertz (THz) research in the late 1980s at Columbia University, only three groups in the USA were actively investigating THz pulses produced from ultrashort laser pulses: the group at IBM led by Daniel Grischkowsky, that at Bell Laboratories led by Martin Nuss and that at Columbia University led by David A...
متن کاملTerahertz-wave Parametric Sources
Terahertz waves are the electromagnetic radiation whose frequency ranges from millimeter waves to the far infrared, shown in Figure 1. While both sides of this range have had a long history of research and development, leading to already commercially available sources, detectors, meters, and many additional devices, the terahertz wave range is still in its infancy, representing the last unexplo...
متن کاملFrontiers in terahertz sources and plasmonics
Terahertz (THz) radiation offers researchers many intriguing possibilities, ranging from fundamental science through to applications in communications, noninvasive imaging, and other areas. The THz region (~0.1 THz to ~10 THz) is often described as the last frontier of the electromagnetic spectrum because of the relatively low maturity level of components and systems that operate in this region...
متن کاملOrganic Broadband Terahertz Sources and Sensors
We review recent research using organic materials for generation and detection of broadband terahertz radiation (0.3 THz−30 THz). The main focus is on amorphous electrooptic (EO) polymers, with semiconducting polymers, molecular salt EO crystals, and molecular solutions briefly discussed. The advantages of amorphous EO polymers over other materials for broadband THz generation (via optical rect...
