Abstract
Circularly polarized optical excitation of a semiconductor microcavity in a transverse magnetic field leads to pulsed laser emission with alternating circular polarization synchronized to the electron Larmor precession. The synchronization originates from the transfer of electron-spin coherence to the dynamics of the optical field. A microscopic theory is developed to analyze the coupled carrier–light-field dynamics.Keywords
