中文摘要： 由于表面等离子体激元具有突破衍射极限、场空间局域增强等特点，成为制作光集成器件的极佳选择。制作各种结构紧凑，具有各种光学性能的表面等离子体光器件已取得长足的进展，但如何对表面等离子体进行有效的调控依然是一大难题。利用声光、电光和克尔效应等进行的调控存在调制范围小、调制精度差、难度大等缺陷。采用光学微流控技术对表面等离子体波导进行调控，由于流体对金属电子密度和电荷分布没有影响，且流体具有相对折射率大，形状可变等特点可以在芯片上构建波导、透镜、光开关和滤波器等光学器件，并实现交换、显示和存储等功能，实现光子器件的微型化和可调化，这对于光器件的集成化无疑是一个有益的尝试。本课题将构建适合光微流操控的微腔结构，探索用光微流技术操控的表面等离子体微腔的新方法和新途径，为制作微流体控光子器件提供理论和实验的重要依据，促成这些新颖的微流控集成光学元器件在未来的信息领域中得到应用。

英文摘要： Surface plasmon polaritons (SPP) has some distinct features that it can overcome the diffraction limit of light and enhance in local space, therefore it becomes a wonderful choice to realize the integrated optical device. The design and fabrication of SPP devices with compact structure and various optical property has achieved good development, but how to manipulate the action of surface plasmon polaritons in devices is still a problem. Manipulation based on acousto-optic, electro-optics and Kerr effect has defects like small manipulation range, low manipulation accuracy and large manipulation difficulty. Fluid has no impact on the metal electronic density and charge distribution, and owns some characteristics like large variations of fluid refractive index and fluid mobility. Therefore, by utilizing the optofluidic technique we can achieve manipulation to the surface plasmon polaritons devices. Waveguides, lens, switches and filters can be integrated on the chip and the function of exchange, display and storage can be realized. The realization of adjustability and microminiaturization of photonics devices is a profitable attempt to the integration of photonics devices. Our research will design the cavity structure fit for the optofluidic manipulation, explore novel approach to utilize the optofluidic technique
