基于变换光学设计的微纳光流控器件性能与应用技术研究

Optofluidics is a burgeoning technology through the fusion of micro/nanofluidics and optics. Optofluidics aims to manipulate light and fluid at micro/nanoscale,and exploits their interaction to create highly versatile devices and integrated systems. This new research area promotes the advancements in optics, biophysics and biochemistry, allowing scientists and engineers to tackle many classical problems with new tools and new research ideas. In this proposal, transformation optics, a frontier method for the manipulation of light will be used to design novel optofluidic devices. The theoretical analysis of the diffusion, convection and centrifugal effect in the micro/nanofluidics will be investigated. The systems with spatially variant permittivity will be identified, offering exciting opportunities for understanding the novel photonic phenomena by controlling and manipulating light in such liquid medium. Novel tunable optofluidic devices such as optofluidic microscopy, liquid waveguide coupler and optofluidic cloak, etc. will be designed. Applications in optical imaging, sensing and manipulating of micro-/nano-substances will be explored based on these transformation optofluidic devices. This proposal attempts to understand the novel photonic phenomena due to the interaction of fluids and light in micro- or nanoscale; and aims to exploit these novel phenomena to provide better solutions for our nation to next generation integrated systems in micro-/nano-photonic devices, biological/chemical analytic systems, environment monitoring etc.
