Abstract

We report a new photoconductive switch having an average output power of 44 μ W , an instantaneous bandwidth of 300 GHz , an output pulse width of 2.2 ps , a peak output power of 1.0 W , and an optical-to-electrical conversion efficiency of 0.5 % when pumped by a palm-sized mode-locked free-space laser at λ = 780.6 nm with an average power of 8.7 mW and an optical pulse width of 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.
