Abstract

Surface THz pulse emission from samples containing 40 layers of InAs quantum dots grown on a AlAs/GaAs Bragg reflector as well as the picosecond photoconductivity of devices manufactured from this material was investigated as a function of the optical wavelength of femtosecond pulses generated by an optical parametric amplifier.
