    "abstract": "We observe the weak coupling of lead sulphide nanocrystals to localized\ndefect modes of 2-dimensional silicon nanocavities. Cavity resonances\ncharacterized with ensemble nanocrystals are verified with cold-cavity\nmeasurements using integrated waveguides. Polarization dependence of the cavity\nfield modes is observed. The linewidths measured in coupling experiments are\nbroadened in comparison to the cold-cavity characterization, partly due to\nlarge homogeneous linewidths of the nanocrystals. The calculated Purcell factor\nfor a single exciton is 75, showing promise toward applications in single\nphoton systems. These novel light sources operate near 1.55 micron wavelengths\nat room temperature, permitting integration with current fiber communications\nnetworks.",
