Nonlinear dynamics of a dipolariton optical parametric oscillator

The dynamics of dipolariton states in a planar microcavity under pumping into the middle dipolariton branch by two laser pulses with close frequencies is investigated. It is shown that both aperiodic and periodic modes of the conversion of pump dipolaritons into idler- and signal-mode dipolaritons can take place under the conditions of exact resonance.
