摘要：

We perform terahertz time-domain pump-probe spectroscopy in low-temperature-grown InGaAs substrate, Temporal evolution of differential optical density shows that photoinduced carrier decays a few picoseconds at low excitation density and several picoseconds at high excitation density. These features of carriers' lifetime and amplitudes of short- and long-lifetime components directly involve emission and detection efficiencies for photoconductive switch, giving its guideline of THz de ices adapted for 1.56 mu m fiber laser.
