Direct measurement of a photoconductive receiver's temporal response by dithered-edge sampling

Opt. Lett. 24, 1771 (1999).
We present the results of a direct measurement of the temporal response of
a terahertz (THz) photoconductive receiver obtained by dithered-edge
sampling. The receiver response has structure that accounts for the
negative-going leading edge of the pulse shape that is often seen in
measurements made with these receivers in a conventional sampling
arrangement. We show that the THz pulse shape measured by conventional
photoconductive sampling is indeed a cross correlation of the pulse with
the measured receiver's response.
