Ultrabroadband photoconductive detection: Comparison with free-space electro-optic sampling
Abstract
The spectral response of a low-temperature-grown GaAs photoconductive (PC) antenna is compared with that of the electro-optic sampling technique for the frequency region up to 40 THz. The spectral response of the PC antenna for broadband detection is found to be determined by the temporal profile of the number of photocarriers injected by ultrashort optical gate pulses.

All three frequencies for B=1 T are within the range of currently available THz photoconductive antennas, and it should be possible to detect the emitted field experimentally.
“All the three frequencies are within the range of currently available THz photoconductive antennas, see e.g. Ref. [44], and it should be possible to detect the emitted field experimentally.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
