Schematic view of (a) double-GL modulator structure coupled with an optical waveguide and (b) band diagram of GLs under a voltage drop between them (shaded areas indicate the states occupied by electrons).
Spatial distributions of the normalized amplitudes of the ac potential and in upper and lower GLs, respectively, for different modulation frequencies .
Normalized modulation depth versus modulation frequency for different electron and hole collision frequencies .
Normalized nodulation depth versus modulation frequency for different plasma frequencies : solid lines correspond to , dashed lines correspond to .
