Light shaping and controlling with micro/nano devices involve fruitfully novel physics phenomena and unknown rules in nature; also it opens a door to nano-photonics and will be the fundamental theory and essential technology in near future. We propose here to investigate surface plasmon devices on metal, silicon-based photonic devices, and waveguide devices in chalcogenide glass, try to understand interaction mechanisms of photon-phonon, photon-lattice, and photon-carrier, etc. Following novel physics phenomenon, we concentrate on development of technologies of light shaping and micro/nano photonic devices. CMOS and ultrafast laser micromachining are employed to manufacture the mentioned micro- and nano- devices. The fine tuning of index of material can be realized by those laser parameters (polarization, wavefront, and energy) which controlled by time shaper and spatial shaper. We focus on the interesting nonlinearity, resonant effect (shows slow light), and mode coupling in micro- nano devices, and the research of the project will open a door to new devices and physics effect.
