Abstract

The Larmor procession of polarized electron spins in a transverse magnetic field causes a synchronized pulsing of the stimulated emission of a semiconductor microcavity. Alternating right- and left-handed circularly polarized pulses are emitted by the vertical cavity laser after excitation of the In0.04 Ga0.96As quantum wells in the resonator with circularly polarized pulses of a picosecond Ti: sapphire laser. The excitation geometry is the Voigt geometry with the magnetic field in the plane of the quantum wells and the optical axis in growth direction. The non-equilibrium carrier and the coupled laser dynamics are successfully analyzed with a microscopic theory.
