Abstract
Abstract Due to the exotic electronic and optical properties, two‐dimensional (2D) materials, such as graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, metal‐organic frameworks, and so on, have attracted enormous interest in the scientific communities dealing with electronics and photonics. Combing the 2D materials with the microfiber, the 2D material‐decorated microfiber photonic devices could be assembled. They offer the advantages of a high nonlinear effect, all fiber structure, high damage threshold, and so on, which play important roles in fields of pulse shaping and all‐optical signal processing. In this review, first, we introduce the fabrication methods of 2D material‐decorated microfiber photonic devices. Then the pulse generation and the nonlinear soliton dynamics based on pulse shaping method in fiber lasers and all‐optical signal processing based on 2D material‐decorated microfiber photonic devices, such as optical modulator and wavelength converter, are summarized, respectively. Finally, the challenges and opportunities in the future development of 2D material‐decorated microfiber photonic devices are given. It is believed that 2D material‐decorated microfiber photonic devices will develop rapidly and open new opportunities in the related fields.
