With the development of optical fiber technology, optical fiber devices have more complex structure, more diverse functions, and more compact size. This poses a great challenge to the microfabrication of optical fiber devices. Femtosecond laser induced two-photon polymerization has the advantages of ultrahigh processing accuracy which breaks through the optical diffraction limit and true three-dimensional processing ability of direct writing without mask. It has unique advantages in the processing of micro/nano-structure, and provides a new idea and possibility for the integration of micro/nano-structure and optical fiber. In this paper, the latest research progress and application prospect of femtosecond laser induced two-photon polymerization for fiber integrated micro/nano-structured devices are introduced.
