Abstract

The cw microcavity optical parametric oscillator (OPO) state is investigated using a theoretical treatment that includes the contributions of the pump, signal, and idler populations to the renormaliation of the polariton energies (the “blueshift”). The theory predicts the pumping conditions under which the OPO switches on, showing that a pump angle 10° is required, but there is no particular significance to the “magic angle” where pump, signal, and idler are all on resonance. The signal and idler renormalization contributions also cause the signal emission to be driven towards the normal direction as the pump power increases above threshold.
