Speech Title: Fiber interferometers fabricated with femtosecond laser

Abstract: Femtosecond laser has become a very convenient and powerful tool to fabricate micro-/nano- structures in different materials and waveguides. Femtosecond laser inscription technique can flexibly modify the refractive index of materials and directly write a variety of structures such as gratings, interferometers and waveguides. We recently developed various kinds of interferometer structures in optical fiber by using femtosecond laser inscription technique and demonstrated their applications in refractive index sensing, high temperature sensing and so on. In this paper, we will review our research work on this topic.
