  text: In our work, we have engineered low capacitance single quantum dot photodiodes
    as sensor devices for the optoelectronic sampling of ultrafast electric signals.
    By the Stark effect, a time-dependent electric signal is converted into a time-dependent
    shift of the transition energy. This shift is measured accurately by resonant
    ps laser spectroscopy with photocurrent detection. In our experiments, we sample
    the laser synchronous output pulse of an ultrafast CMOS circuit with high resolution.
    With our quantum dot sensor device, we were able to sample transients below 20
    ps with a voltage resolution in the mV-range.
