Abstract

Colloidal PbS and PbSe quantum dots are mixed with polystyrene and spincoated on top of a silicon-on-insulator microring notch filter. We demonstrate that the light propagating through the ring resonator strongly interacts with the quantum-dot doped thin film. This allows us to efficiently tune the output of the notch filter by varying the quantum-dot size and concentration. As a result, the hybrid devices can exhibit critical coupling only for a single resonance or display a constant extinction ratio over a wide spectral range. Considering the promising nonlinear optical properties of colloidal quantum dots, our results open new pathways for all-optical signal processing applications on a silicon platform.
