ABSTRACT
The photoconductive antennas based on multi-energy arsenic-ion-implanted GaAs and semi-insulating GaAs are demonstrated to have a useful bandwidth beyond 20 THz for a gating laser pulse width of 15 fs. The bandwidth and signal-to-noise ratio are compared with those of reference photoconductive antennas based on low-temperature grown GaAs. © 2003 American Institute of Physics.

    Carbon was implanted into GaAs at doses between 1013 and 5×1014 cm-2, either by itself or with Ga coimplantation at room temperature or 200 °C. Activation percentages as high as 40% were obtained for C+Ga implants at 5×1014 cm-2 compared to <3% for C implantation only. The peak...

    The absorption saturation relaxation time in light- and heavy-ion-irradiated GaAs saturable absorbers has been measured as a function of the temperature in the range from 7 to 300 K. For both types of samples, the relaxation time is shorter than 4 ps at 7 K. A regular increase of this time with...
