Terahertz emission from GaAs and InAs in a magnetic field
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. Ultrashort pulses of THz radiation were produced at semiconductor surfaces by photoexcitation with a femtosecond Ti-sapphire laser. We recorded the integrated THz power and the THz emission spectrum as a function of mag...

متن کاملTerahertz emission from Ga1−xInxSb
We report an experimental study on terahertz THz emission from Ga1−xInxSb with 0 x 1. THz emission is excited by femtosecond near-infrared laser pulses. For this material system THz emission is maximized for an In mole fraction x 0.5. The maximum in THz emission occurs as a result of carrier compensation NA NB for this specific material composition. The THz emission from n-type InSb is twice as...
متن کاملTheory of magnetic-field enhancement of surface-field terahertz emission
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 consists of two parts: a Monte Carlo simulation of the dynamics of carriers generated by a subpicosecond optical pulse, and a calculation of the resulting THz radiation emitted through the semiconductor surface. The magne...
متن کاملEmission of terahertz radiation from SiC
We report the emission of strong coherent broadband terahertz radiation from 6H-silicon-carbide SiC excited with optical pulses. The measured terahertz spectral signal-to-noise ratio is better than one thousand. We determine that the terahertz radiation is generated via second order optical nonlinearity optical rectification . We present a measurement of the ratio of nonlinear susceptibility te...
