In-fiber integrated optics is an attempt to use silica fiber as a substrate, integrating various optical paths or optical components into a single fiber, to build a functional optical device or component, to realize a micro optical system, achieving various functions. In-fiber integrated optics is expected to be a new branch of photonics integration. This integration technique enables conve-nient light beams control and manipulation inside in one fiber. It also provides a research platform with micro and nano scale for interaction between lightwave and microfluidic maters. In this paper, we briefly summarize the main ideas and key technologies of the in-fiber integrated optics by series integration examples.
