Abstract
We report the realization of a monolithic vertical-cavity, surface emitting micro-optical parametric conversion nanostructure, triply resonant with the parametric frequencies, allowing parametric oscillation with ultra-low pump power threshold. The photonic phase-space naturally provides triple resonance for the parametric frequencies, together with built-in cavity phase matching for the pump wave at normal incidence. Parametric oscillation is observed in both the strong and weak exciton-photon coupling regime, allowing high operating temperature. Signal and idler beams can be collected at 0{ring operator} or at finite angles. The OPO threshold is low enough to envisage the realization of an all-semiconductor electrically-pumped micro-parametric oscillator.
