Differential photoconductive sampling with a resolution independent of carrier lifetime

Abstract

We present a novel approach to photoconductive sampling with a resolution which is virtually independent of the carrier lifetime and is governed solely by the circuit-limited gap charging time. Using photoconductors with a carrier lifetime of 150 ps, accurate measurement of a 65-ps-wide electrical signal is demonstrated and the actual resolution is believed to be 10 ps.
