Two-mode squeezing in polariton four-wave mixing
Résumé
We present an analytical model describing polariton four-wave mixing oscillation in semiconductor microcavities. The noise spectra of the intensity difference of the light emitted by the oscillating polariton modes are calculated. It is shown that the two-mode squeezing depends essentially on the ratio of the photonic to the excitonic fraction of the polariton modes. This ratio can be adjusted freely by changing the cavity-exciton detuning. A comparison with available experimental results indicates that a significant intensity difference squeezing can be expected for realistic experimental situations.
