New nanocomposite materials with large optical nonlinearity are important for the development and miniaturizing of active components and integrated circuits for all-optical signal processing and computing. To enable on-chip integration with silicon microelectronics nonlinear signal processing components compatible with silicon nanophotonics need to be developed. In this paper, we study the nonlinear optical response of silicon-based photonic bandgap (PBG) structures filled with PbSe quantum dot (QD) materials and experimentally demonstrate the feasibility of a new class of nonlinear nanophotonic devices for all-optical signal processing based on such microstructures. Active tuning is demonstrated for both out-of-plane components, with one-dimensional porous silicon PBG microcavities and in-plane components, using one-dimensional PBG waveguide-based microresonators.
