Abstract
The temporal evolution of the polarized emission spectra of spinor exciton-polariton condensates in double tunnel-coupled potential traps in a high-Q GaAs/AlAs microcavity at 2 K under resonant laser pumping with picosecond pulses has been studied in the time range up to 1.5 ns. An estimate of the spin relaxation time of the condensate τS ∼ 10 ns is obtained. The influence of the symmetry of the trap potential on the energy spectrum of the polariton modes and on the polarization dynamics of the spinor condensate in the tunnel-coupled potential traps is discussed.
