Abstract
A semiconductor-laser strobed photoconductive sampling gate for the measurement of ultra-high-speed electronic signals on coaxial lines is reported. For the short response (<100 ps) and high responsivity (>0.1 A/W) at the 830 nm laser wavelength the sampling gate uses a miniaturised (8×8×1 ¿m) epitaxial GaAs photoconductor on a broadband tapered coplanar 50 ¿ microwave structure.
