Chemical and physical systems undergoing change display spectral signatures from the
radio frequency to the X-ray region of the electromagnetic spectrum. This has led to the …

The book describes the most advanced techniques for generating coherent light in the mid-
infrared region of the spectrum. These techniques represent diverse areas of photonics and …

We have studied terahertz (THz) emission from InAs and GaAs in a magnetic field, and find
that the emitted radiation is produced by coupled cyclotron-plasma charge oscillations …

We provide a review of the different schemes for generating terahertz (THz) radiation using
photoconductive emitters excited by femtosecond lasers. The discussion is concerned …

We present a theoretical treatment of surface–field THz generation in semiconductors, which
explains the power enhancement observed when a magnetic field is applied. Our model …

We present a theory of the magnetic field enhancement of terahertz (THz) emission from
photogenerated carriers in the surface depletion region of a semiconductor. A combination …

We present frequency-dependent absorption coefficients and refractive indices of sulfur-
containing biomolecules in the far-infrared region measured by terahertz (THz) time-domain …

An international team of experts describes the optical and electronic properties of
semiconductors and semiconductor nanostructures at picosecond and femtosecond time …

A compact, high-power emitter of half-cycle terahertz (THz) radiation is demonstrated. The
device consists of an epitaxial InAs emitter upon a GaAs prism and produces THz pulses …

The excitation fluence and magnetic field dependence of terahertz (THz) radiation power
from InAs is investigated. At low excitation fluence, an enhancement of the THz-radiation …
