英文摘要： As one of the important contents of lab on a chip, integrated optical devices based on-chip particle manipulation has become an international hotspot. The research progress can help to reveal novel optical phenomena in mesoscopic scales and develop high-performance optical devices. However, the traditional optical waveguides confine the light in the high-index core, which limits the effective interaction between the light and particle and presents a challenge for the development of on-chip optical manipulation. This project aims to combine the slab photonic crystal waveguide and the refractive index regulation, and study the interaction mechanism between particle and slow light in waveguide, which could provide a novel method to effectively enhance the particle-light interaction. The main contents in this project include: (1) interaction mechanism between particle and slow light in slab photonic crystal waveguide; (2) optical micro-manipulation mechanism and experimental realization based on the refractive regulation in slab photonic crystal waveguide. The key scientific problems to be solved are theoretical model of the interaction between particle and slow light, and design of high-performance tunable slab photonic crystal waveguide based optical micro-manipulation device. The obtained progresses are helpful to reveal the physical mechanism of particle manipulation based on slow light, and develop high-performance particle controller on chip. It will also provide a new theoretical and experimental foundation for the development and applications of on-chip optical micro-manipulation techniques.
