A microscopic theoretical analysis of coherent charge oscillations in optically excited GaAs- AlxGa1−xAs double wells and resulting infrared light emission is presented. Our non-phenomenological study is based on generalized Boltzmann–Bloch equations which account for the laser field within the rotating-wave approximation, the dynamics of interacting electron-hole pairs in the heterostructure, excitonic effects, and the destruction of phase coherence by the inter-carrier Coulomb interaction. Emitted THz electromagnetic pulses are analyzed. © 1996 American Institute of Physics.
