Abstract

The formation of the ground states in a GaAs/AlGaAs asymmetric coupled quantum-well is analyzed with the use of coupled-mode theory. Based on perfect work condition of traveling-wave modulators, the GaAs/AlGaAs coupled quantum-well is optimized and the optimal coupled quantum well has a large electro-refractive index change at low absorption loss.
