The delay time between the beginning of optical illumination and the onset of switching in the transient response of semi-insulating GaAs high-power high-speed photoconductive switching devices is investigated in this letter. The field-and laser-energy-dependent optical absorption coefficient is used to explain the experimentally observed open-state-field and laser-energy-dependent delay time. Our calculations agree with the experimental results.
