Enhanced spontaneous parametric down-conversion in plasmonic nanocavities for on-chip quantum photonics
We demonstrate SPDC from thin film TiO2 embedded in plasmonic nanocavities, achieving enhanced cross-polarized photon-pair generation with sub-200 nm cavities. Characterizations include emission spectrum, polarization, and power-dependence studies, alongside second-order correlation (g(2)) measurements. Observed temporal correlations confirm photon-pair generation, highlighting the potential of this approach for scalable quantum photonic applications.
