We introduce a scheme of single photon emission based on four-wave mixing ina three mode system with weak Kerr-type nonlinearity. A highly populated lowerenergy mode results in strong stimulated scattering of particle pairs out ofthe central mode, which consequently limits the central mode occupation. Thus,the system can be reduced to a $\chi^{(2)}$ nonlinear medium with greatlyenhanced interaction constant. As a model setup we consider dipolaritons insemiconductor microcavities. Using the master equation approach we show strongantibunching under continuous wave pump, which largely exceeds the conventionalblockade mechanism. Finally, using a pulsed excitation we demonstratetheoretically a triggered single photon emitter in a weakly nonlinear systemwith 33% emission probability.
