Three-band excitonic Rabi oscillations in semiconductor quantum wells

Optical Rabi oscillations in atomic two-level systems and excitonic Rabi oscillations in two-band semiconductors are already well established. In contrast to two-level (or two-band) Rabi oscillations, three-level (or three-band) Rabi oscillations offer a rich variety of oscillation dynamics involving both radiative and nonradiative (Raman) transitions. We analyze excitonic three-band Rabi oscillations in semiconductor quantum wells and study, in particular, the role of band-coupling effects and Coulomb effects.
