The Rao Yutai 2nd class award for fundamental optics ——Ultrafast tunable organic nonlinear photonic crystals

As a novel photonic material, photonic crystals possess unique photonic bandgap properties and can manipulate the propagation of photons. Tunable photonic crystals，the position and width of whose bandgap vary with the external parameters, are important elements for integrated photonic devices. We report on the development of ultrafast tunable organic photonic crystals based on the excellent optical nonlinearity of organic conjugated polymers.
