Abstract
Two superlattice p-i-n diodes connected in series to a constant dc bias, i.e., in the symmetric self-electro-optic effect device (S-SEED) configuration, exhibit pronounced oscillations of their transmission intensities immediately after optical pulse excitation of one of the diodes. The temporal variations directly reflect the transmission-voltage characteristics due to successive Stark ladder resonances, and they depend strongly on the amount of the illumination power and on the pulse width. The observed oscillatory behavior is explained by changes of the voltage balance between the two diodes induced by photogenerated charge transport.
