Abstract
Analytical and numerical solutions for coherent excitations of quantum beats in a coupled quantum well by two phase-locked optical pulses ar e shown using the density-matrix formulation. It is demonstrated that active control of terahertz radiation due to charge oscillations cause d by quantum beats in a coupled-quantum-well structure is possible usi ng two-femtosecond optical pulses with a time delay shorter than the e xciton dephasing time. Our theoretical results agree very well with ex perimental observations.
