Terahertz (THz) science and technology have greatly progressed over the past two decades
to a point where the THz region of the electromagnetic spectrum is now a mature research …

Many exciting terahertz imaging applications, such as non-destructive evaluation,
biomedical diagnosis, and security screening, have been historically limited in practical …

Over the past three decades a new spectroscopic technique with unique possibilities has
emerged. Based on coherent and time‐resolved detection of the electric field of ultrashort …

Time-resolved, pulsed terahertz spectroscopy has developed into a powerful tool to study
charge carrier dynamics in semiconductors and semiconductor structures over the past …

Overview and Scope. THz radiation, with frequencies in the range of 0.1 À20 THz, can probe
physical phenomena such as low-energy excitations and carrier dynamics in electronic …

We present a scheme for exploiting the nonresonant second‐order nonlinearities in electro‐
optic media to extend the bandwidth of coherent spectroscopy in the far‐infrared using …

Organic π‐conjugated crystals with second‐order optical nonlinearity are considerably
attractive materials for diverse terahertz (THz) wave photonics. An overview of the research …

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 …

We have wrapped metallic cylinders with strongly absorbing metamaterials. These resonant
structures, which are patterned on flexible substrates, smoothly coat the cylinder and give it …

Ultrafast optics has undergone a revolution in the past two decades, driven by new methods
of pulse generation, amplification, manipulation, and measurement. We review the …
