英文摘要： Laser interaction with micro-nano structures in metal or dielectric is one of the core scientific problems in the field of optoelectronics. Metal-filled photonic crystal fiber (MPCF) has the property of flexible structure design and the surface plasmon resonance effect. MPCF provides a new carrier and breakthrough for this problem. In this project, the silica MPCF has been simulated and designed based on the theory of optical waveguide and the surface plasma. Because of high temperature heating, the problem of silica crystallization will appear in the MPCF fabrication process, and this problem will be solved. The relationship between the structure parameters of MPCF and the key fabrication parameters such as temperature, pressure and time will be revealed. Silica MPCF containing metal wire or metal film can be prepared by reasonable filling or coating method. The characteristics of MPCF, such as loss, polarization, nonlinear, coupling and filtering, will be tested in this project. The mechanism and characteristics of surface plasmon resonance in the MPCF will be revealed by the combination of theory and experiment results. Developing of MPCF can greatly promote the quality of the photonic crystal fiber and extend its application scope. The polarization filter and sensor based on MPCF are expected to become the next research hotspot in the field of special optical fiber. Because there are metal wires with size of micron or nanometer along the MPCF's axial, optical carrier signal can be directly transmitted to metal by MPCF. Due to the special structure, MPCF could be used to solve the problem of photoelectron interconnection in the scale of subwavelength.
