We report the generation of nonclassical states of light through parametric fluorescence in a silicon photonic crystal cavity with equally spaced resonances. A bichromatic cavity design was adopted to obtain a comb-like resonance spectrum, while mode-selective tuning by laser-assisted local oxidation was used to fine adjustment of the resonance frequencies after fabrication, thus achieving almost perfect equally-spaced modes. Both stimulated and spontaneous four-wave mixing were observed. The generation of correlated single photon pairs was confirmed through coincidence measurements.

Abstract
We report the generation of nonclassical states of light through parametric fluorescence in a silicon photonic crystal cavity with equally spaced resonances. A bichromatic cavity design was adopted to obtain a comb-like resonance spectrum, while mode-selective tuning by laser-assisted local oxidation was used to fine adjustment of the resonance frequencies after fabrication, thus achieving almost perfect equally-spaced modes. Both stimulated and spontaneous four-wave mixing were observed. The generation of correlated single photon pairs was confirmed through coincidence measurements.File in questo prodotto:
