We demonstrate enhanced emission of solution-processed sparse lead sulfide quantum dots (QDs) coupled to confined as well as propagating modes in silicon photonic crystals at near-infrared communications wavelengths. In the cavity case, by using cold-cavity characterization using on-board waveguides or cross-polarization techniques, we show that the coupled QD lineshape is identical to the cold-cavity spectra. For the photonic crystal waveguides (PhCWGs), we use transmission spectra for the PhCWG as well as three-dimensional finite difference time domain techniques to validate enhancements due to the propagating mode. The observation of room-temperature quantum electrodynamics using postfabrication QD integration techniques is promising for further studies.
