Abstract

Experiments of a lateral semi-insulating GaAs photoconductive semiconductor switch triggered by nanosecond serial laser pulses were reported. The switches were insulated by solid multi-layer transparent dielectrics. Jitter-free electrical pulses with steady voltage amplitude from the 0.5 mm-gap GaAs switches were observed. Its change of amplitude was less than 1.1%, the triggered jitter-time was less than 10ps, and pulse width was up to sub-nanosecond. The Jitter-free and steady speciality of electrical pulses from the photoconductive semiconductor switch was analyzed. It was indicated that ultra-fast electrical pulse with steady voltage amplitude and pico-second triggered jitter-time can be obtained by controlling switch trigger condition and optimizing switch design.
