Quantum complementarity of microcavity polaritons

The spontaneous and self-stimulated parametric emission from a semiconductor microcavity after resonant pulsed excitation is measured. The emission of the lower polariton branch is resolved in two-dimensional momentum space, using either time-resolved or time-integrated detection. Employing two pump directions, we experimentally probe polariton quantum correlations by exploiting quantum complementarity. Polaritons in two distinct idler-modes interfere if and only if they share the same signal-mode so that "which-way" information cannot be gathered. The experimental results prove the existence of polariton pair correlations that store the "which-way" information.
