Stochastic single shot polariton condensate polarization pinning at high temperatures
Abstract
We resolve single-shot polariton condensate polarization dynamics, revealing a high degree of circular polarization persistent up to T = 170 K. The statistical analysis of pulse-to-pulse polariton condensate polarization elucidates the stochastic nature of the polarization pinning process, which is strongly dependent on the pump laser intensity and polarization. Our experiments show that by spatial trapping and isolating condensates from their noisy environment it is possible to form strongly spin-polarized polariton condensates at high temperatures, offering a promising route to the realization of polariton spin lattices for quantum simulations.
