Terahertz emission from (100) InAs surfaces at high excitation fluences
The radiated terahertz field from (100) InAs surfaces under excitation at fluences of millijoules per centimeter squared has been studied in detail in order to identify the main generation mechanism. We find that the terahertz emission depends strongly on pump polarization, and that the predominant emission mechanism appears to be the surface nonlinear optical response of the InAs crystal. A sa...

متن کاملTerahertz 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 کاملQuantitative comparison of terahertz emission from (100) InAs surfaces and a GaAs large-aperture photoconductive switch at high fluences.
InAs has previously been reported to be an efficient emitter of terahertz radiation at low excitation fluences by use of femtosecond laser pulses. The scaling and saturation of terahertz emission from a (100) InAs surface as a function of excitation fluence is measured and quantitatively compared with the emission from a GaAs large-aperture photoconductive switch. We find that, although the ins...
