英文摘要：

Microfluidics is the basis of micro total analysis system （μTAS） and the research spotlight in Micro-Electro-Mechanieal Systems （MEMS） now. With the development of microfluidics and the cooperation with other technologies, many new areas, especially microfluidic optical devices, come into being. It is possible that the miniaturization, arraying, low-cost and precise control of the optical devices are realized by the cooperation between microfluidic technology and optical devices. Some typical optical devices and applications are presented, including variable-focusing microlens, display device, optical switch, tunable optical fiber and grating.
