Introduction
In nanophotonics one focuses on studies of the classical and quantum natures of light generation, transportation, modulation, transformation, and detection processes. By manipulating photons, one can construct ultracompact, high-speed, broad bandwidth, low energy consuming consumption photonic devices and technologies, which have huge tremendous and wide potential applications in information, energy, health, and environment technologies and industries. Our team is engaged in the following researches:

Basic physics and application of photonic crystals. Photonic crystal has unique properties in band gap, band dispersion, and photon density of states, and is looked upon as “Semiconductor of Light”. Our team has investigated silicon photonic crystals for integrated devices and high-Q cavities, polymer Kerr nonlinear photonic crystals for ultrafast optical switching and logic devices, ferroelectric nonlinear photonic crystals for high-efficiency frequency conversion, and magneto-optic photonic crystals (MOPC) for nonreciprocal electromagnetic devices.

Basic physics and application of plasmonic nanostructures. Surface plasmon polaritons (SPPs) in metal nanostructures have many unique properties such as highly localization and giant resonant enhancement of optical field, and highly sensitivity to environment. Our team has investigated surface plasmon resonance (SPR) control of metal nanoparticles and its interaction with fluorescence and Raman molecules, gain media, nonlinear optical, optoelectronic, and photocatalytic materials, and explored approaches to manipulate the transport, scattering, and diffraction of SPPs in metal nanostructures.

 

Motivations
The objectives of our research on the basic physics and application of photonic micro/nanostructures are to have deep understanding on and make use of the behaviors and laws of light transport and light-matter interaction at micro/nanometer scales. We will harness these basic research results to develop integrated devices and technologies based on photonic crystals, develop high-sensitivity biochemical sensing and environment detecting technologies based on plasmonic nanostructures, and explore quantum state manipulation technologies based on photonic micro/nanostructures.
