These devices are enabled by the enhanced light-matter interaction in photonic crystals, and serve as the building blocks of on-optical information processing circuits.lasermodulatoroptical communicationsoptical nonlinearityphotonic crystalquantum dotquantum welltext::conference output::conference proceedings::conference paper
