摘要

We report a new photoconductive switch having an average output power of 44 (mu)W, an instantaneous bandwidth of approx300 GHz, an output pulse width of approx2.2 ps, a peak output power of approx=1.0 W, and an optical-to-electrical conversion efficiency of approx0.5percent when pumped by a palm-sized mode-locked free-space laser at lambda velence 780.6 nm with an average power of 8.7 mW and an optical pulse width of approx-230 fs. The switch is made from an ErAs:GaAs epitaxial layer inside a resonant optical cavity and coupled to a planar three-turn square spiral antenna.
