Ultrafast photonic crystal nanocavity lasers: We have recently demonstrated ultrafast photonic crystal nanocavity lasers with response times as short as a few picoseconds and demonstrated direct modulation speeds far exceeding 100GHz. |

Nanoplasmonics We are designing plasmonic structures that can confine light on-nanometer scales. These structures opens up new opportunities for sensing. |

Slowing light on-chip using photonic band gap materials: Using coupled cavity arrays, we have recently demonstrated slowing light on-chip more than two order of magnitude. These structure are important for non-linear effects and optical information processing. |

High-throughput biosensor integrated with microfuidics : We are designing plasmonic and photonic crystal structures to develop label-free, high-throughput, portable and ultra-sensitive biosensors to detect biomolecules. We are also integrating with microfluidics to handle small volumes of biological samples. |

Nano/Bio-patterning:We are developing new techniques to pattern biomolecules on the surface of nanophotonic and plasmonic devices. The above AFM picture shows captured viruses on the surface. The capture antibody spots with dimension as small as 10um are patterned with a modified AFM tool (Nanoenabler from Bioforce). |
