The integration of quantum emitters with nano-photonic circuits enables quantum optic experiments on monolithic silicon chips. However, controlling the positioning of single nano-scale emitters or arrays of single emitters relative to nanophotonic structures is a major challenge for realizing integrated quantum light sources supplying photonic integrated circuits with single-photons.
In our work, we employ Silicon(IV) Phthalocyanine (SiPc) molecules as nano-emitters, which show distinguished photostability [1]. We embed SiPc molecules into a PMMA host matrix, which allows for thin-film application on top of prefabricated tantalum pentoxide (Ta2O5) waveguides. Lithographic patterning of the PMMA-thin film then achieves the desired overlay accuracy with respect to the nanophotonic devices. Here we report on the excitation of the molecules and collection of their fluorescent light through nano-photonic waveguides, thus paving the way for integrated quantum photonic experiments.
