Abstract

We propose a polariton hyperparametric oscillator (PHO) based on a semiconductor photonic dot at the micro/nano scale. By theoretical derivations and numerical calculations, we find that the PHO not only amplify weak signals like general large-planar polariton amplifiers, but also depress strong signals unusually. The coexistence of such signal amplification and depression can cause a stable signal emission being almost independent of the excitation instabilities in the strong-excitation regime. It has been verified that the instability of the signal emission, increasing with the increase of the excitation instabilities, is only about one to two percent deviation from its average intensity even under strong instable excitations. Hence, the PHO can serve as a stable optical-signal emitter in micro/nano optical systems.
