Temporal terahertz radiation wave forms emitted from ion-irradiated and LTG GaAs strip lines and detected by a LTG GaAs dipole antenna.
Fourier-transformed amplitude spectrum of the temporal wave forms emitted from ion-irradiated and LTG GaAs strip lines.
Temporal terahertz radiation wave form detected by ion-irradiated strip lines. A LTG GaAs dipole antenna is used for emission. The insert is the Fourier-transform amplitude spectrum.
Pump-power dependencies of the peak amplitudes of the wave forms emitted from ion-irradiated (open circles) and LTG GaAs (full triangles) dipole antennas.
