ABSTRACT
We demonstrate tunable frequency-converted light mediated by a χ(2) nonlinear photonic crystal nanocavity. The InP-based cavity supports two closely spaced localized modes near 1550 nm, which are resonantly excited by a 130 fs laser pulse. The cavity is simultaneously irradiated with a nonresonant probe beam, giving rise to rich second-order scattering spectra showing nonlinear mixing of the different resonant and nonresonant components. We highlight the radiation at the sum frequencies of the probe beam and the respective cavity modes. This would be a useful, minimally invasive monitor of the joint occupancy state of multiple cavities in an integrated optical circuit.
