摘要:
Interference between single-photon and two-photon absorption is investigated theoretically to demonstrate coherent control of the emission of THz radiation from semiconductor double wells. Variation of the relative phase between the two concurrent pump pulses controls both the final density of photogenerated electron-hole pairs, predominantly excitons, and the intensity of microwave emission associated with coherent charge oscillations in the double well. ©1998 American Institute of Physics.
